1.2. CURRENT STATUS AND PLANNED REGIONAL WIND POWER DEVELOPMENT

1.2.1 Programme of wind power development in Vietnam

Nowadays, with seriously environmental pollution and exhausted fossil energy sources, many countries in

the world have started to study various forms of renewable energy to replace traditional forms of energy.

Renewable energy is very diverse, for example wind energy, solar energy, tidal energy, geothermal

energy and biomass energy. According to [1], the Vietnamese Government has prioritized policy to

developing power generated from renewable energy resource, gradually increase the density of this

energy resource. It is expected that total capacity of wind power source will increase from the insignificant

level (about 31 MW) at present to nearly 1,000 MW by 2020 and nearly 6,200 MW by 2030.

Vietnam is located in the range of 80 ÷ 23

0 Northern latitude in the area of monsoon tropical climate, with

two main seasons a year, the regions having good wind potential only account for 2% of the territorial

area, mostly coastal regions and highlands, most of the other regions have wind regime of 2 – 4 m/s.

Wind potential in some coastal regions and islands which have wind speed of over 4 m/s (at the altitude

of 12m above the ground) can apply wind power sources [1]. According to World Bank’s report wind

potential in Vietnam at the altitude of 65m is as follows:

Potential (MW) 401,444 102,716 8,748 452

Wind potential in Vietnam concentrates mostly in the southern central coastal region and southern coastal

provinces such as Tra Vinh and Soc Trang.

1.2.2 Current status and planned wind power development of Binh Thuan province

Binh Thuan province has 4 topographical forms: sand hill and coastal sand dune, alluvial delta, hill region

and low mountainous regions. Natural area of the province is 7,812.9km2 including 49,644.8 ha of unused

land. With the above terrain and existing natural conditions Binh Thuan has much potential for renewable

energy. Considering wind potential Binh Thuan province has abundant wind all year, high wind speed is

very beneficial to wind power development.

From 1998 to 2000 tens of households in Tuy Phong district used household power-generating wind fans

but the efficiency was not high due to lack of experience in equipment repair and maintenance.

From 2006 to 2010 Binh Thuan province gave priority to wind power in its development objective with a

series of big wind power projects. At present, in Binh Thanh commune, Tuy Phong district are 20 wind

power turbines with total capacity of 30MW (1.5MW per turbine) which have been generating power to

supply for 100kW electric network of the province.

According to [2], wind potential of Binh Thuan province has the following characteristics:

Binh Thuan is a province with great wind energy potential which is capable of developing wind power at

industrial scale in all districts/towns except for Duc Linh and Tanh Linh districts.

According to wind atlas the most potential districts/towns are coastal districts/towns in the East, namely

Tuy Phong, Bac Binh, Phan Thiet, Southern Ham Thuan, Northern Ham Thuan, Tham Tan and La Gi.

2.4. IMPACTS ON LOADING CAPACITY OF REGIONAL ELECTRICAL NETWORK

2.4.1 Normal operating mode, without Tuy Phong wind power plant

In this mode, calculation results of active power, reactive power trend distribution of 110kV network at

220/110 kV transformers and 110kV lines without Tuy Phong wind power plant are presented in the

following table. Detailed diagram is given in the appendix:

It can be seen that in this operating mode only transformer station of Ham Thuan 220/110kV

hydroelectric plant is overloaded, 110kV lines operate normally within admissible limits.

25

26

2.4.2 Normal operating mode with Tuy Phong wind power plant (30MW)

In this mode, calculation results of active capacity, reactive capacity trend distribution of 110kV network

at 220/110 kV transformers and 110kV lines with Tuy Phong wind power plant are presented in the

following table. The calculation applies to 2 cases: maximum load in rainy season and minimum load in

dry season. The detailed diagram is given in the appendix:

The table of results shows that in maximum mode in rainy season Tuy Phong wind power plant (30MW)

connected to the electric network of Binh Thuan province reduces load of transmission lines and cuts

down load for two 220/110kV transformer stations, namely Ham Thuan and Dai Ninh hydroelectric

plants (since Tuy Phong wind power plant supplies power directly for local load, thus reducing power

flow mobilized from the system). In minimum mode in dry season all lines and 220kV transformer

stations operate normally within admissible limits.

2.5. IMPACTS ON VOLTAGE VARIATION AT CONNECTION POINTS AND ADJASCENT NODES

After calculating the capacity trend results of voltage at connection points of wind power plant and

adjacent nodes in modes are obtained: maximum load in rainy season without wind power plant;

maximum mode in rainy season with Tuy Phong wind power plant (30MW); minimum mode in dry

season with Tuy Phong wind power plant (30MW). Results of 220kV and 110kV voltage comparison

are presented in the following table. The detailed diagram is given in the appendix.

The table shows that voltage at most of 220kV and 110kV voltage nodes falls within the range of

+10%/-5% Udm. Voltage at some nodes is improved when there is a wind power plant operating such as

Ninh Phuoc, Ninh Son, Mui Ne and Phan Ri, etc.

2.6. IMPACTS ON SHORT-CIRCUIT CURRENT

Using PSS/E programme short circuit current at nodes with or without wind power plant can be

calculated as follows.

Tuy Phong node the node currently connected to Tuy Phong wind power plant (30MW). 1 phase short-

circuit current increases greatly, up to 44% also at Tuy Phong node. In conclusion, connection of wind

power plant to the electric system increases short circuit current at connection points and adjacent

nodes.

2.7. IMPACTS ON HARMONIC

With wind turbines using digital converter these converters will generate harmonics during continuous

operation of turbine. Two important parameters to be considered are current of each harmonic and total

current of all harmonics. According to IEC 61400-21, standard on wind turbine harmonics with

amplitude of less than 0.1% of basic harmonic it can be skipped.

2.7.1 Harmonic wave overlapping

Normally, in a wind farm are many wind power generating units. During continuous operation of each

wind power generating unit using digital converter, various volumes of harmonics will be generated

depending on location and capacity of such unit. In extreme case when harmonics are in the same

phase angle the amplitude of harmonic will be biggest. In case of different types of wind turbines it is

difficult to determine harmonic volume simultaneously generated by these turbines. So, wind power

standard IEC 61400-21 suggests a formula to estimate value of each harmonic type.

Wherein: WtN - number of wind turbines at main connection points;

ihI , - level h harmonic wave current of turbine i;

β - exponent, given in following table.

31

Harmonic number β

h < 5 1.0

5 ≤ h ≤10 1.4

h > 10 2.0

In the event wind turbines have the same capacity and the same type of control, harmonics will have

the same phase angle and factor β = 1 should be used with every harmonic.

Formula (1) does not consider using transformers with various line winding groups, it is possible to

eliminate a certain number of harmonics. In the event of using these transfomers it is necessary to

further work out their impacts (for example: transformer with triangle winding group may emilinate

harmonics which are multiple of 3 such as 3, 6, 9, etc.)

2.7.2 Impacts of harmonic on electrical system

Main impacts of harmonic on electric system are normally capacity loss, electric power quality,

equipment overload such as capacitor, reactor and especially resonance and fluctuation in the system.

With wind power plants directly connected to electric system through a short cable the whole plant can

be seen as an unit at the main connection point. Harmonic current of this source is calculated by

formula (1). Voltage harmonics are calculated by current value multiplies impedance at connection

points in the system.

With wind power plants connected to the system through long cable (wind turbines are located on the

beach) it is advisable to study more carefully impacts of harmonics on the system since resonance is

highly possible. Resonance frequency may change due to operating conditions of transmission

network. Therefore, harmonics of voltage noise should be calculated at the highest level of total

resonance at connection points of PCC which can be shown by using formula (1) to calculate impacts

of all wind turbines in the plant on voltage harmonic noise.

In extreme case, the calculation of voltage harmonic noise will be applied to designe harmonic filter if it

is necessary.

2.7.3 Special simulations

In some cases, filters are used right at wind turbines to avoid resonance that may damage turbine.

In other cases, level 3, 6, 9… harmonics may appear which are zero sequence waves. Since the

standard IEC 61400-21 requires simulation only at low side of generator end transformer, in this case,

study is needed to point out the problems that may arise by these harmonics by measuring and

simulating harmonics at high side of transformer. (Zero sequence harmonics may cause triangle coil of

this transformer to be overloaded).

32

2.7.4 Study results of 300MW wind power plant in Binh Thuan province

Binh Thuan wind power plant is the first big capacity wind power plant in Vietnam using 15 FL 1500kW

wind turbines made by Fuhrlander. These wind turbines have IGBT-PMW converters with capacity of

30% turbine capacity. Major strength of this converter is that it creates relatively small harmonic

volume.

With wind power plant in Binh Thuan province the main connection point is 2kV side of the wind power

plant. Since this plant has small capacity it can be considered that above system is linear and has very

big capacity compared to the wind power plant. Therefore, major study results are as follows:

The biggest harmonic is level 4 harmonic with current value of 0.7% Idm.

Total current of all harmonics is 1.1% Idm.

Total voltage of all harmonics is 0.17% Udm.

The biggest voltage harmonic is level 5 harmonic, with value of 0.09% Udm.

It can be seen that calculated values of harmonics are very small and fall within admissible range of

IEC 61000-3 standard.

2.8. IMPACTS ON FLICKER

2.8.1 Flicker

According to definition of electric power quality flicker is a quantitative characteristic for human feeling

under the pressure of light flickering in a time unit. Major cause of light flickering is change in voltage

amplitude of luminaries for difference reasons (mostly due to change in active capacity big reaction of

source or load). This phenomenon is quite popular when using air turbine equipment, due to following

reasons:

• Continuous change in wind turbine capacity, wind speed.

• Processes of turning on/off of wind turbine.

Flicker of wind turbine is normally calculated according to IEC 61400-21 standard. According to this

standard, short-term flicker - Pst and long-term flicker Plt should be calculated. These values should be

smaller than admissible value Pst < 1.3 Plt <1; To calculate flicker values the following parameters are

needed:

• Short circuit capacity at connection point Sn;

• The angle between resistance and reactance at connection point ψ;

• Flicker factor c(ψk);

• Pitch factor of flicker, frequency kf;

• Conversion factor of voltage kU;

• The number of most short-term turn-off times N10;

• The number of most long-term turn-off times N120;

In case of continuous operation, flicker is calculated by the following formula:

If calculation results do not meet the standards on voltage flickers some measures are needed to

reduce flicker to below admissible value. The most popular measure is using high quality and fast

reaction voltage adjusters such as FACTS (SVC or STATCOM).

Results of short-circuit current calculated are as follows:

Short-term and long-term flickers are stipulated differently according to standards or grid code of each

country. Normally, values range from 0.3 to 1.3. Calculation results show that flicker values of Binh

Thuan wind power plant are quite far from admissible values. Therefore, Binh Thuan 30 MW wind

power plant can operate normally without back end measures to meet the requirements concerning

voltage flicker.

The voltage at most nodes falls within admissible limits of +10%/-5% Udm. Except for Thuan Nam node

(-5,77%) is lower than admissible limits.

In normal operating mode Ham Kiem – Phan Thiet 110kV line is frequently overloaded at peak hours in

three Alternatives. It is proposed to increase the section of Ham Kiem – Phan Thiet 110kV line to AC-

240 with a length of 14.8km.

Thus, the voltages at nodes of Binh Thuan’s electrical network improve better and are in admissible

limits when those wind power plants are in operation. Detailed voltages are presented in the table

3.6. IMPACTS OF HARMONIC ON ELECTRICAL SYSTEM

3.6.1 Input assumptions

In this case, it is possible to consider the main connection point of the plant as Phan Ri 110kV station,

from this station are two 110kV lines to the station of Dai Ninh hydroelectric plant. Calculation results

are based on the following assumptions:

• 220kV system above Dai Ninh plant is considered to be great.

• Ignoring the impacts of harmonic on other 220kV stations (in this case, harmonic will have the

most impact on the system).

• The lines are replaced by p diagram.

• Wind turbines are similar and have 2MW capacity, the system consists of 155 wind turbines.

• The transformer is replaced by transformer impedance.

• 200kV system is replaced by impedance.

• Ignoring surface effect.

• The main connection point of the plant is 110kV side of Phan Ri station.

• The connection cables in the plant are considered as the sole condenser.

3.6.2 Results of harmonic calculation

Therefore, the main results of the study are as follows:

• The biggest harmonic is level 4 harmonic with current value of 0.6% Idm.

• Total current of all harmonics is approximately 0.94% Idm.

• Total voltage of all harmonics is 0.56% Udm.

• The biggest voltage harmonic is level 4 harmonic, with value of 0.45% Udm.

It can be seen that values of calculated harmonics are very small and fall within admissible range of

CHAPTER 4. CONCLUSIONS AND RECOMMENDATIONS

4.1. CONCLUSIONS

The appearance of Tuy Phong wind power plant (30MW) in the transmission electrical network of Binh

Thuan province has impacts on loading capacity of the network and the voltage at connection points. If

generated wind power is maximum, it will reduce the load for two 220kV transformer stations, Ham

Thuan and Da Nhim hydro electric plants due to the capacity of Tuy Phong wind power plant supplying

for local load and reducing the capacity mobilized from the system. For the voltage at connection points

wind turbines are able to improve voltage (better), since these turbines are able to adjust voltage within

narrow range (compared to normal power plant). When connecting wind power plant to the system, the

short circuit current at connection points and surrounding joints tends to increase but still below current

admissible limits.

The calculation of harmonic wave and voltage flicker shows that the impact of 30MW wind turbine on

the system is very small, within admissible limits.

When connecting 340MW wind power plants to the system of Binh Thuan province, overload is

possible, 110kV lines discharging the capacity of wind power plant at the moments of maximum and

minimum load. The electrical system should be improved and upgraded to ensure the loading capacity

of lines, but avoid wasteful investments should be avoided. Alternative 1 has weak structure of

electrical network, lots of new lines should be built compared to the other two Alternatives. Alternative 3

has bigger volume of investment than Alternative 2. Alternative 2 has the least investment capital (only

02 circuits of Hoa Thang – Hoa Thang and Tuy Phong – Phan Ri wind power plant lines should be

additionally built). However, in the event of N-1 failure at the end of Phan Ri to Phan Thiet line, Tuy

Phong, Phu Lac and Phuoc Huu wind power plants should reduce generation to avoide overload of

remaining lines. This can completely be done by establishing inter-control system among stations.

The voltage of local electrical network is improved when connected wind power plants are available,

since DFIG wind turbines are able to adjust the voltage within narrow range.

The appearance of 340MW wind power plant will increase short-circuit current on local electrical

network but still falls within admissible limits.

The calculation of harmonic wave and voltage flicker show that total distortion of harmonic wave and

voltage flicker with 340MV wind power fall within admissible limits.

This research does not delve deeply into selecting the optimal Alternative but focuses on analysing

possible impacts on electrical system such as loading capacity of lines, voltage at joints, short circuit,

harmonic wave and voltage flicker. The selection of Alternatives should consider economic targets of

each Alternative.

85

4.2. RECOMMENDATIONS

As analyzed above, the selection of solutions to improve, upgrade electrical system to transmit all wind

power source to national electrical network depends much on economic and technical targets of each

wind power plant, more specific research into these targets is needed.

The wind potential in Binh Thuan – Ninh Thuan provinces is great; however, the load is small.

Therefore, demand for transmitting big capacity to other distant load areas arises. To select the best

transmission Alternative, it is necessary to study general solutions to electrical network with long-term

vision of 10-20 years to build a safe, consistent, sustainable, economical and effective electrical

network.
