摘要
固定式电容机械投切无功补偿系统存在实时性差、只能分级投切和机械装置动作频繁等缺点;动态无功补偿系统SVC采用TCR和TSC组合方式,可对无功功率进行动态、连续补偿;针对某一具体工程应用,确定了SVC主电路方案和相关技术参数,设计了基于DSP2000系列TMS320F2812的动态无功补偿系统控制装置,详细介绍了控制器的原理及实现技术以及软件功能,给出了系统采样信号、触发信号等理论与实测波形,实验结果表明动态型静止无功补偿装置具有运行可靠、控制精度高、调节时间短及实时性好的优点。
The SVC founded in MC has many disadvantages such as badly real-time track,compensate in group,machine switch frequency and so on,whereas,the SVC founded on TCR and TSC can compensate vars dynamically and continuously.This paper gives a plan of the main circuit of SVC and the related technology parameter,also designs the dynamic SVC controlling device based on DSP TMS320F2812.It introduces the principle and related technology of the SVC controlled device,and the software function of it in detail.At the same time,it also gives the wave of sampling signal,thyristor trigger pulse whether in theory or in fact.Experimental result shows that the dynamic Static Var Compensator has reliable,high control precision,short adjustment time and good real-time advantage.
