High reliability: The SCR is installed in low voltage circuit, not in main circuit, so, the withstanding voltage is just 1% of main circuit voltage. Low harmonic contents: THD is below of 5%, which comply with related national criterion, if the multiple connections are adopted, the THD can be reduced below of 1.2%. Small dimension: the dimension of MCR is about 2/5 of TCR. It can be able to connect in high voltage power grid, the cost and floor space are reduced dramatically. Fast response time(100~300ms), it can fully meet the demand of dynamic reactive power compensation of power equipments. No need of cooling devices, which reduce the fault rate, maintenance cost and floor space. 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: The inductive reactive current in main circuit can be adjusted through changing low voltage DC to regulate main circuit impedance fast and smoothly, meanwhile, through cooperating with capacitor bank paralleled in bus bar, reactive power compensation demand can be realized on bus bar, and dynamic response and improved power factor can stabilize bus bar voltage. Choosing reactor parameters properly connected in series with capacitor bank, the compensation on fundamental wave can be obtained, and the harmonic also can be filtered. 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 1000KV, and the maximum capacity reach to 320MVar. 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. Wooden case (Fumigation).
Principle APF is a new power electronic equipment which can dynamically filter harmonic with variable amplitude and frequency and compensate reactive power, it overcome the shortages of traditional LC filter and obtained the better compensation characteristics than passive filter. The following diagram is schematic diagram of APF, where, Vs is AC power supply, nonlinear load is harmonic source, it generates harmonic and consumes reactive power. APF is composed of instruction current operational circuit and compensation current generation circuit, the instruction current operational circuit is mainly to inspect current contents in harmonic current and reactive power of compensation object, and the compensation current generation circuit generates actual compensation current according to instruction current, the main circuit adopted PWM converter. Technical Features: Compensate any order harmonic with variable amplitude and frequency and different reactive power dynamically, and has a high-speed response time to the change of compensation object, it is hard to generate harmonic resonance with power grid impedance. It can implement compensation on single harmonic source and reactive power source and also implement centralized compensation on many harmonic and reactive power sources. Adopt full-bridge PWM converter to generate compensation current, the power unit is 5th generation IGBT, it is working under the high-frequency switching. Power circuit and control circuit adopted modularized structure or plug-in unit, same module can be replaced, which enhanced the reliability and maintenance. DSP high-speed checking and operation ensure harmonic checking and compensation control correct; It has intelligent supervisory control function, the working state and operation parameters are displayed in real-time, meanwhile, faults can be self-diagnosed; it also has remote communication interfaces, the real-time monitoring can be realized through PC. With perfect protection functions, the main circuit adopted three-phase three wire or three-phase four wire, it is designed to shunt APF, very easy and safe to operate. The master chip adopted latest floating-point DSP F28335 of TI Company and FPGA of ALTERA Company to make the system have powerful processing capacity, the sampling adopted AD7606 with 16 bits of AD Company to ensure control precision. APF can be used in power grid alone or can be combined with other passive filters together to realize hybrid filter with best ratio of performance to price.
