Why choose SVC of MCR TypeÂ
The advantage of MCR-typed SVC
The MCR-typed SVC was based on traditional saturation reactor technology; it was put forward by Russia scientists. They introduced the concept of magnetic valve creatively to just make the small section of iron core saturation, which solved the high harmonic problems caused by traditional saturation reactor, because all iron cores in traditional saturation reactor are excessive saturation, then result in nonlinear harmonic. At the same time, the SVC of MCR type reduced the dimension, weight and noise of entire system; it has many advantages, such as: low harmonics, fast response time, high voltage withstanding level, stable operation, small floor space and long service life. Therefore, the SVC of MCR type is quickly spreading in Russia, Ukraine, America, India, China and other countries. It plays a very important role in improving power quality, decreasing reactive power loss, stabilizing power grid voltage and enhancing the reliability of power grid operation.Because MCR-typed SVC adopted advanced micro-electronics technology, it can regulate reactive power demand and compensation on bus bar accurately:
Because the SVC of MCR is free of frequent switching from mechanical parts, then it avoids surge and over-voltage impact caused by MSC, which enhances the reliability and the service life of the equipment, as well, protects the other instruments.
The SVC of MCR type fully absorbed advantages and functions of TCR-typed SVC by comparison; it solved the problems of smooth regulation which can not be realized by MSC and TSC, and also overcome some disadvantages of TCR-typed SVC. Because the reactor is connected to high voltage main circuit directly in series, it must stand extra high voltage and ultra high voltage. At present, the highest voltage of reactor in our country reach to ***0KV, and the maximum capacity reach to **0MVar. The reactor also has over-load function; it will not generate big damage to system except heating, while, the thyristors in TCR-typed SVC is connected to high voltage circuit directly, the over-voltage will result in faults and break. So it is very stable for MCR-typed SVC to operate under the high voltage circuit with free of maintenance.

Frequently Asked Questions
Â
A. The SVC of MCR type adopted iron core reactor, while TCR-typed SVC adopted air-core reactor, if the loss of MCR-typed SVC is higher than the loss of SVC with TCR type?
Â
At first appearance, it seems that the loss of MCR-typed SVC is higher than the loss of SVC with TCR type because of its iron core, but after respective loss analysis, we found:
In conclusion, the loss of MCR-typed SVC is very low and just about 1/2 of TCR-typed SVC.
Â
B. The SVC of MCR type adopted saturation reactor with iron core, does it generate big noise?
Â
No matter transformer or reactor, they both generate noise, but the main reason of noise is not because of saturation (but of course, the higher the magnetic density, the bigger the noise, but it can be decreased or eliminated by technique improvement), it depends on manufacturing process. At present, the transformer technology in China is becoming more and more advanced; the noise of big transformer is decreased below *0db, it fully complies with State Environmental Protection Standards. We cooperate with the first-class transformer/reactor manufacturer to control the reactor noise below *0db.

Application industrial fields
A complete set of SVC system can be used to generate constantly varied inductive and capacitive reactive power with fast response time. So far, SVC system has been extensively used in electric power system and industrial field such as:
Rolling mill, Electric arc furnace and ladle furnace, Electric railway traction substation, Hoists and other heavy industrial loads, Long distance power transmission, Wind power plant and Secondary substation (*6KV to **0KV) Etc.
