| 摘 要： | 现有低压线路无功补偿装置不具备谐波监测与保护功能,由于谐波干扰造成装置退出运行、电容器损坏的事故频繁发生,严重影响装置安全运行和电网经济运行水平。应用数字信号处理器TMS320C32设计实现了低压线路无功补偿装置的谐波实时监测与保护,实验研究与现场运行表明,该方法能够有效地提高现有装置抵御谐波干扰的能力和并联补偿电容器运行的可靠性。

| Abstract: | With the objective of overcoming the shortcomings of low voltage line reactive power compensation device, based on harmonic data from the running field, actual harmonic level, system voltage, system circuits and running situation of the compensation device, the harmonic protection module is designed with digital FFT method in software program. The digital signal processor is used. The real time monitoring and protecting of Harmonic wave for low voltage line reactive power compensation device is realized. Experimental results and field running situations indicate mat this device is effective. |
