摘要
SVC的控制算法是静止无功补偿的关键。要及时和准确地跟踪无功功率的变化,实现对SVC的控制就要求控制算法必须快速和准确。电子及计算机技术的发展使得更加复杂和精确的算法得以应用于SVC的控制中。在电网电压定向矢量变换算法的基础上,以DSP芯片TMS320F2812为核心,开发了一套新的晶闸管控制电抗器(TCR)的控制装置。使用ALTERA公司的CPLD芯片实现脉冲的触发,触发方式灵活,可以根据需要快速地跟踪负荷的情况进行三相平衡或者不平衡的无功补偿。
The control arithmetic is the key of SVC control.Precisely tracking the change of reactive power in time necessitates the rapid and precise control arithmetic.The development of electronics and computer technology enables the application of more complex and precise control arithmetic.In this paper,a new type of thyristor controlled reactor device is developed.With TMS320F2812 of DSP chip as core,a set of new TCR control device is developed.The flexible trigger method realized by CPLD chip enables the balance or imbalance reactive power compensation by the necessity of three-phase load change.
