On August 12, 2020, the magnetically controlled shunt reactor (MCSR) of the Inner Mongolia 500 kV Bazhong substation supplied by NR Electric, completed all tests and was officially put into operation.

The successful operation of the system further consolidates the advantage of NR in the field of MCSR application.

magnetically controlled shunt reactor

The magnetically controlled shunt reactor (MCSR) can adjust the DC of the control winding, and change the reactance value and reactive capacity of the reactor, to realize the continuous regulation of the grid voltage.

It has the advantages of high reliability, continuous regulation, and fast response speed.

multi-electrical quantity compound control

NR closely follows the field demand and provides integrated protection & control solutions

This project is the first application of MCSR in the Inner Mongolia power grid. NR closely follows the field demand and provides integrated protection & control solutions based on a unified software and hardware platform, covering monitoring, communication, excitation, protection, and other domains, realizing integrated monitoring and improving the level of overall automation.

It is equipped with an intelligent excitation system and multi-electrical quantity compound control with patented technology. 

high-reliability design

The strategy ensures the safe operation of the system. At the same time, it has a fast response ability of less than 1 second, which is far better than the technical requirements of 3 seconds.

It adopts a high-reliability design and full redundancy design of the control unit, excitation regulator, power rectifier, and other equipment to ensure the reliable operation of the system.

superior performance

The test results all reached the international advanced level, and the indicators were better than expected

During the implementation of the project, strict tests were carried out on the primary and secondary equipment, including grid-connected impact, winding current rise, self-excitation switching, step response, and other tests. The test results all reached the international advanced level, and the indicators were better than expected.

The operation results show that the PCS-9578 reactor control system, PCS-9150 sequence control system, PCS-917 protection system, and other primary and secondary equipment provided by NR are stable in operation and superior in performance, which are highly recognized by the owner.

wind power energy

The project has been put into operation, providing strong support for the export of abundant wind power energy in Wulatezhong Banner, Inner Mongolia, ensuring the safe and stable operation of transmission lines.

UHV magnetically controlled shunt reactor has a good application prospect in the fields of long-distance transmission and renewable energy application. NR has experience in the design, supply, and operation of magnetic-controlled shunt reactor projects in different countries, and has formed a complete technical system that can provide complete solutions and integrated services for power grids and enterprises.
