1、摘要近年来,由于电网容量的增加,对电网的无功要求也与日增加,同时对电能质量的要求也越来越高。传统无功补偿装置很难达到单位功率因数的补偿,电网无功功率不平衡将导致系统电压的巨大波动,严重时会导致用电设备的损坏,出现系统电压崩溃和稳定破坏事故。TSC是目前广泛使用的无功补偿方式,具有结构简单、费用较低的优点;注意标点论文首先介绍了无功功率补偿的意义和现状,无功功率的作用。介绍了TSC基本结构和原理,建立了的数学模型,对稳定性进行了分析这个有么。其次,在分析TSC特点后,确定了整体控制策略:TSC以无功功率为主要
2、控制目标,而大部分无功功率由TSC补偿,本文重点介绍TSC静止无功补偿稳定系统电压的研究。不通顺吧为验证本文研究的控制策略的有效性,在MATLAB/SimiLINK混乱环境下对TSC进行了仿真研究。对TSC系统进行了设计,仿真。结果验证了该控制算法的有效性,能增加系统的稳定性,减少电容器动作的次数。通过SIMULINK建立了TSC仿真模型,对仿真波形图进行了分析,结果表明TSC型静止无功补偿在提稳定系统电压方面能满足要求,显示出该无功补偿方式具有较大的应用价值。关键词:无功功率静是否需要标点止补偿稳定电压-
