Purpose of Electrochlorination plant

As experienced from operation of shore-line nuclear power plants and thermal power plants in India all

the components of service water supply systems on suction and delivery lines are subjected to fouling.

Biofouling is characterized by hundreds of types of seaweeds and foulants and inconsiderably depends on

sea water salt content and temperature. The main fouling components are seaweeds, mussels, barnacles,

hydroids, polychaets, diatomaceous species.

The Kudankulam NPP service water supply system is intended for continuous cooling sea water supply of

the loads while fouling of the above system components such as screens and fine-mesh rotary screens and

water conduits considerably increases hydraulic resistance of the service water supply system and reduces

heat exchange on the loads.

Hence continuous and periodical treatment of the service water with sodium hypochlorite solution is

worldwide used for protection of the cooling water systems by electrolysis or liquid chlorine to provide

protective concentrations against fouling.

Purpose of SCAD system in Electro chlorination plant

The Electrochlorination Plant is completely managed by a PLC based system . All the measures and

signals coming from the field are connected to the PLC. These are directly connected on I/O cards set of

side to the CPU running the SCADA Software.

The SCADA system is intended to control the operation of the Electrochlorination plant by monitoring,

modifying the parameters of plant.

Toolbar

The toolbar represented below is used by the user to visualize alarms and for the navigation among the

Main screens

Parameter Status Screens

1.Filter Status

The Filter status should be represented as follows

a)When the filter in stop position

b)When the filter is in operation

c)When the filter is in backwash state

d)When the filter is in alam state

The Step: indicates the number of step the filter [ie. Filter state] is in progress

2.Blower Status

The Blower status should be displayed as follows

a)Red Colour- When a blower motor is in stopped state.

b)Green Colour - When a blower motor is in running position.

c)Ash Colour- When the state of a blower motor is “in movement” (change state from stop to

running) .

39

d)Yellow Colour [Flash] - When after a planned run time of the blower motor the MCC has not

returned a signal of the motor isrunning.

e)White Colour- When the blower motor fan is in stand-by is represented .

3.Filter Motor Status

The seawater filters are provided with motors. The status of motors of the seawater filters should be

displayed as follows

a)Red Colour- When a motor is in stopped condition

b)Green Colour- When a motor is in running position

c)Ash Colour- When the state of a motor is “in movement” (change state from stop to running)

d)Yellow colour [Flash]- When after a planned run time of the motor, theMCC has not returned a

feedback signal that the motor is running

4.Manual Valve Status

The manual valve status should be displayed as follows

a)Red Colour - When a valve is in closed condition

b)Green Colour - When a valve is open condition

c)Ash Colour - When a valve is in movement

40

d)Yellow Colour - When after a planned time, the manual valve doesn't not reaches the correct

position

5.Differential Pressure Switch Status

The differential pressure switch details should be represented as follows

a)Yellow Colour - When the Warning level differential pressure has reached in the filter

b)Red Colour - When the Alarm level differential pressure has reached in the filter

6.Pump Status

The pump status should be represented as follows

a)Red Colour - When the pump-motor is in stopped state

b)Green Colour - When the pump motor is running

7. Process variable and Threshold values

The process parameters such as temperature, flow, pressure, diffrential pressure, level etc which are

displayed in the Main screens are viewed and edited as follows

Process parameter display

The process parameter instantaneous values are displayed inside a rectangular box as shown below

Parameter instaneous value

41

In case of overcoming of a threshold [level1, level2 ] the colour inside the bow will change to yellow at

exceeding the threshold level1 and red colour at exceeding the threshold level2

Threshold Leve1

Threshold Level2

Inorder to view the alarm delay time of a digital input, click on the corresponding parameter [ex.

Differential PressureSwitch Input], the Preset-time screen appears

Forcing of Values

Inorder to force an parameter value,its threshold level1 & level2, alram delay time the user should click

the rectangular box in which the parameter is displayed.On clicking the Analog setpoint screen

appears.The user should enter the new values in the corresponding text boxes and click on the value

Forcing check box to force the values. The real and history trend of the parameter can also be viewed

from the analogs setpoint screen by clicking the corresponding button

42

8.Arrow

The arrows are used

to change from one

page to another, if

there is a continuity

between a page of

supervision and the

other, the arrow

allows to access the

section of plant tied

to that it visualizes.
