1 Preface
The length of the construction site for Hokuriku Shinkansen (between Nagano Station and Kanazawa Station) is about 228km in track length. For this con-struction project, we manufactured and delivered substation facilities for feeder systems, power distri-bution facilities, electrical train line facilities, and associated equipment.
Fig. 1 shows the location of power transmis-sion and distribution substation facilities for Hokuriku Shinkansen. In the feeder substation facilities, there is a boundary section where two different frequen-cies of 50Hz and 60Hz are used in power supplies. It was a big challenge to solve the frequency differ-ence of the facilities and build a unique system. This paper introduces how we face such challenges and provides the outline of the supplied facilities.
2 Feeder Substation Facilities
The project sites are at four posts: the Shin-Kurobe Substation (SS), Shin-Takada Sectioning
Post (SP), Shin-Kuwadori Sub-Sectioning Post (SSP), and the Shin-Nou SSP.
The Shin-Kurobe SS receives utility power through a 2-circuit 154kV transmission line from Hokuriku Electric Power Company and the received power is stepped down to single-phase 2-circuit 60kV by a Scott-connection transformer. The 60kV single-phase power is converted into single-phase 30kV through an auto-transformer. The resultant power is fed to commercial train cars in operation. Fig. 2 shows a main-circuit connection diagram for the Shin-Kurobe SS.
2.1 Power Receiving Circuit-Breaker (CB)We delivered a 168kV Gas-insulated Circuit-
Breaker (GCB) to the Shin-Kurobe SS. Since the GCB is adopted, features of compactness and light-ness can be attained. Table 1 shows the ratings and Fig. 3 shows an external appearance of a 168kV GCB.
2.2 Feeder Transformer A 70MVA Scott-connection transformer was
delivered to the Shin-Kurobe SS. The major features

AbstractHokuriku Shinkansen for linking Kanazawa Station with Tokyo Station is a
projected Shinkansen Line Plan. Part of the route between Tokyo Station and Nagano Station already began com-
mercial operation in 1997 by the name of Nagano Shinkansen. The section between Nagano Station and Kanazawa Station is an extended part of the overall section.
Hokuriku Shinkansen (between Nagano Station and Kanazawa Station) was inaugurated in the spring of 2015. As a result, the required time to travel between Tokyo Station and Kanazawa Station is reduced from 4 hours to 2.5 hours. The section between Kanazawa Station and Tsuruga Station is scheduled to be inau-gurated in an estimated 10 years from now.
Major electrical facilities we delivered involve substations for feeders and railway track facilities.

of this transformer are described below. (1) Since the transformer main body was designed for a low-noise configuration, it does not require a building for its transformer noise. As a result, site construction work was very simple. (2) Thanks to the progress of analytical technolo-gies for electrical field intensity measurements, it was possible to substantially attain compactness. (3) Since the neutral point of the Scott-connection transformer was fully insulated, it was possible to omit the Point-M surge arresters.
Table 2 shows the ratings and Fig. 4 shows an external appearance of the 70MVA Scott-connection transformer.
2.3 Feeder CB An ecological tank-type Vacuum Circuit-Breaker
(VCB) has been introduced. This type is eco-friendly because dry air is used as the insulation medium. Since this is SF6 gas-free, it contributes to Climate Control.
In addition, since there is no need for the
recovery of gas and maintenance for current break-ing parts, the life cycle cost is also reduced. Table 3 shows the ratings and Fig. 5 shows an external appearance of the 72/36kV eco-tank type VCB.
2.4 Changeover Switch A solenoid-operated changeover switch of the
low operating current type was delivered. A high withstand voltage type was delivered to the post where the different-frequency boundary section is situated. This program applies to the posts where the Shin-Takada SP and the Shin-Itoigawa SP are located. Table 4 shows the ratings and Fig. 6 shows the 36kV changeover switch.
2.5 Track Feeder Control Switchgear For each post, we installed a functionally pack-
aged control switchgear for the railway. Fig. 7 shows the monitoring and control panel and Fig. 8 shows the system configuration diagram of the Shin-Kurobe SS. The major features of the switchgear are specified below.

(1) A large-capacity and high-speed Programmable Logic Controller (PLC) is adopted. This equipment makes it possible to take high-speed actions for the interlocked operation. High reliability is assured due to the redundant configuration. (2) By adopting the integrated type next-genera-tion digital relays, it realized a high-function and high-performance system. High reliability is assured due to the redundant equipment configuration. (3) Units are mutually connected through Ethernet Local Area Network (LAN). Such an approach is effective in building a system where the system is comprised of some units and equipment by other corporations. (4) In consideration of reduction of CB operating frequencies at the time of field interlock testing, a simulator panel was introduced. (5) In order to improve system reliability, optical cables are used for bus tie breaking circuits and
simplified remote control circuits because the opti-cal cables are less influenced by noise. (6) A live line insulation monitor unit is provided for the local low-voltage and battery control panels in order to realize labor-saving maintenance.

(7) An instrumentation unit is installed separately for data logging. This unit displays the presently measured values and shows daily and monthly reports. It is in charge of maintenance work and improvement of system efficiency. (8) Major auto-functions of power distribution pan-els for substation are as follows:
(a) Automatic changeover for power receiving and reclosing circuit for power receiving (b) Power feeding reconstruction, feeder reclos-ing circuit, and automatic feeder opening (c) Individual automatic interlocking of change-over and automatic standby unit changeover in case of changeover switch malfunction (d) Automatic 89AT opening in the case of 63AT in operation
2.6 Measures against a Different Frequency The section between Shin-Takada SP and
Shin-Itoigawa SP is operated at 50Hz. The two sec-tions neighboring both sides of this section are operated at 60Hz. In consideration of any adverse influence upon facilities due to the different frequen-cies, measures as described below were taken. In principle, any 50Hz power supply is not extended to the section of 60Hz because such an extension results in damage of equipment. (1) Common use of dual frequency equipment
In the section between Shin-Takada SP and Shin-Itoigawa SP, ratings of winding coil equipment are specified as both 50/60Hz frequency. Fig. 9 shows the different-frequency boundary section and the scope of dual frequency equipment produc-tion range. The applicable posts are the Shin-Takada SP, Shin-Kuwadori SSP, and Shin-Nou SSP.
(2) Measures against asynchronism (a) Measures against extension of gap voltage In a 50/60Hz boundary section, a phase displace-ment of 180°can occur at the largest. Fig. 10 shows a phase displacement in a different-frequency boundary section. If a phase displacement of 180°arises in a feeder voltage of 30kV, the result-ant gap voltage may rise up to 60kV. For this rea-son, the delivered changeover switch is designed to have a gap voltage of 60kV so that it can withstand such a high voltage. The objective post is the Shin-Takada SP. (b) Measures against stray currents on the rail-way train line and signaling system In consideration of the effect of stray currents at a different frequency to signaling facilities, the fol-lowing measures were taken. The applicable post is the Shin-Takada SP.
(ⅰ) Insulation area is provided to rails so it gives resistivity to any different frequency power flowing. As a result of taking such a measure, arcs are

60Hz 50Hz
Displacement of 180°
In an area where 50Hz and 60Hz frequency are met, a phase displacement of 180°appears periodically. In this case, a volt-age twice the regular level is generated.

generated by the effect of a feeble potential dif-ference when train cars pass through this sec-tion. As a countermeasure, a rail insulation short-circuiting device is installed so that the rail insulation can be short-circuited when train car passes by. (ⅱ) A Booster Transformer (BT) is installed in the mid-section so that stray currents can be returned to their own post. (ⅲ) In order to minimize the effect of different frequency, coaxial cables are adopted for exter-nal cables.
(3) Protection against an accident from differ-ent-frequency contact
When a 50Hz power supply comes in contact with a 60Hz power supply, a beat-state fault current appears at a period of 0.1 seconds and a frequency of 55Hz. Fig. 11 shows a current waveform in case of a different-frequency contact. In such a case, a normal Relay 44F and Relay 50F may fail to detect or detect incorrectly. In order to avoid such a failure, different-frequency contact relays are separately adopted. Features of these relays are specified below.
(a) 95F This relay is a device to detect a 55Hz signal component in the case of a different-frequency contact. (b) 68F This relay is a device to detect a frequency component level and a contact ratio of the oppo-site substation. The applicable posts are the Shin-Kurobe SS and the Shin-Takada SP.
(4) Measure against sampling frequency changeover Protective relays used in the 50Hz section are
set to make sampling at 50Hz in order to detect the occurrence of a fault. If a 60Hz power supply should
intrude into this 50Hz section, normal fault detection cannot occur due to inconsistency in sampling. In order to solve this problem, we have adopted a sys-tem where a 60Hz changeover signal is propagated shortly before the intrusion of a 60Hz source. The protective relays are designed to have a function so that the setting can be changed over between 50Hz and 60Hz when this signal input is entered in the relay.
The applicable posts are the Shin-Takada SP, the Shin-Kuwadori SSP, and the Shin-Nou SSP.
3 Local Substation Facilities
Our supplied posts for Hokuriku Shinkansen are the Nishi Kasahara power Distribution Post (DP), the Itoigawa DP, and the Shin-Kurobe DP, totaling 3 posts. The electrical facilities for power distribution posts receive power from the power company through a 6.6kV single- or double-circuit line. Emergency power generating equipment is also installed so that electric power can be kept supplied even though the incoming utility power line experiences a power outage. The power distribution system also supplies power to stations along the railway line. It feeds the power for station building lighting, disaster prevention facility, machinery facil-ities, and signaling and communication facility. Fig. 12 shows a single-line connection diagram of the Shin-Kurobe DP.
3.1 High-Voltage Switchgear CB, disconnecting switches, and other essen-
tial devices are accommodated in an enclosed switchgear. CBs are of the solenoid operation type. The designing policy has focused on compact design and reduction of control power capacity. In order to emphasize non-flammability, mold type transformers are adopted.
At the Nishi-Kasahara DP, a dry-air insulation switchgear is adopted. Since the main circuit is put in an enclosed tank, this equipment is not influenced by installation conditions and assures freedom from electric shocks. In addition, long service life is assured and maintenance is easy. Fig. 13 shows a medium-voltage switchgear at the Nishi-Kasahara DP. Fig. 14 shows a medium-voltage switchgear at the Itoigawa DP.
Each power distribution post is a facility to receive power from the electric company and sys-tem impedance is generally large. The effect of volt-
When mutually different frequencies of 50Hz and 60Hz are com-bined, the resultant voltage waveform appears at a frequency of 55Hz, repeating a strong phase and a weak phase in a period of 0.1 seconds.

MEIDEN REVIEW Series No.165 2015 No.328
age drop due to inrush current of transformer core excitation therefore becomes an issue. To solve this issue, medium-voltage load break switches with an inrush current restraint function are used. In addi-tion, transformers are adopted to restrain the exci-tation inrush current within less than three times.
3.2 Power Distribution System Configuration The Nishi-Kasahara DP employs the large-capac-
ity high-speed PLC and the interlinking of each piece of equipment is configured with hardware circuitry.
At the Itoigawa DP and the Shin-Kurobe DP, automatic interlocking treatments are carried out for power outage and restoration. A redundant configu-ration is therefore adopted for the large-capacity high-speed PLC to improve reliability. Digital relays are assembled in each circuitry unit to establish an attributed configuration. Fig. 15 shows a system configuration of the Nishi-Kasahara DP and Fig. 16 shows that of the Itoigawa DP.
3.3 Auto-Periodic Inspection Function The Itoigawa DP and the Shin-Kurobe DP are
provided with an automatic checking function for interlocking with power outage and restoration. At the time of maintenance service, this function makes it possible to change operation from grid power to stand-alone generator operation by giving a mimic power outage signal from the monitoring and control panel so that interlocked power outage sequence can be executed. After the specified period of time, the mimic power cut signal is reset in order to exe-cute the power restoration sequence for recovery from a service interruption. This function allows for effective maintenance work.
3.4 Measuring Equipment Measuring equipment is installed to collect
data for the current value display and daily/monthly report logging. For medium-voltage CBs, contact opening and closing time is measured to identify the adequacy of CB operation. By this meas urement, it is possible to discover any faulty CB operation resulting from aging deterioration developed in each medium-voltage CB. By virtue of these functions, we designed effective maintenance work.
4 Railway Train Line Facilities
Tunnel disaster prevention Disconnecting
Switches (TDS) are installed in seven delivery posts. When a fire breaks out inside the tunnel, the TDS sections the accident spot and makes it possi-ble to feed power to sound circuits. This facility is important because it has a role to take train cars out of the tunnel.
4.1 TDS Since these disconnecting switches are installed
inside the tunnel, the enclosed type GIS was adopted in consideration of environmental conditions. Table 5 shows its ratings.
4.2 Monitor Control For the control of TDS, monitor control is car-
ried out from a nearby substation post in simplified remote control mode. Control power is fed from the battery control panel installed on the site.
5 Postscript
According to the projected Shinkansen Line Plant, Hokuriku Shinkansen will be extended as far as Osaka via Tsuruga.
Various facilities delivered from us will contrib-ute to safe and fast operations of Shinkansen. We expect that this Shinkansen will be an important means of transportation for the people traveling between Tokyo and Hokuriku Area.
Lastly, we express our deepest gratitude to all individuals who provided us valuable suggestions and cooperation relating to the supply of these facil-ities.
