| 摘 要： | 提出了一种新的电力电容器调容方法,该方法基于PWM控制原理,用电力电子开关控制两组电容器的投切,通过调节控制脉冲的占空比连续调节电容.该方法克服了目前无功补偿装置中分组投切电容器时电容有级差的缺点,同时减少了补偿所需电容器组的数量.采用MATLAB中的PowerSimSyetems对该方法进行仿真分析,仿真结果与理论值一致.

| Abstract: | A new kind of method of adjusting capacitance for electric power capacitor was put forward,which is based on PWM principle,uses electronic switch to control 'on and off' of two sets of capacitors and implements continuous adjustment of capacitance by changing duty ratio of control pulse.The method overcomes the shortcomings that there is capacitance rank difference in reactive compensation equipment used commonly now when capacitor is switched by grouping,and reduces the number of capacitor group used for compensation.The method was simulated and analyzed with Power Sim System in MATLAB software,the results is consistent with theory analysis. |
