摘要
基于大功率全控型电力电子器件GTO的静止无功补偿装置具有自关断特性,在以DSP控制技术的支持下,通过实时检测电网无功功率的变化,自动发出GTO通/断控制脉冲,快速投切电容器,实现对供电线路无功功率的跟踪调节。该装置比普通晶闸管补偿装置(TSC)的可靠性高。在实现三相共补与分相补偿时,具有响应速度快、控制简单、噪音和损耗小、可靠性高、结构简练等优点。
A static var compensator based on high-power full-controlled power electronic device GTO has the self-shutdown feature.Supported by DSP control technology,any change of reactive power in the power grid can be detected in real-time,and sent to GTO automatically with on-off control pulse to achieve the tracking and adjusting of reactive power in the supply line.The device has a higher reliability than the ordinary thyristor compensator（TSC）.It provides the advantages of fast response,simple control scheme,low noise,low loss,high reliability and so on if the compensations of three phases and single phase are realized.
