摘要

在电力系统中,DSTATCOM可以用来保证配电系统中从配电母线引出的电流是平衡的和正弦的。主要出现电能质量问题。DSTATCOM是一种并联补偿装置,一般用于解决配电系统中的电能质量问题。它会导致整个系统性能的下降。DSTATCOM的控制策略对实现目标起着重要的作用。提出了一种基于混合遗传算法的DSTATCOM自适应控制策略,对PID系数进行整定。利用这种控制方法,补偿器可以将PCC电压稳定在规定值附近。在MATLAB环境下开发了一个分布式电力系统,验证了所提方法的有效性。

Controlling study of D-STATCOM based on Hybrid Genetic Optimization PID algorithm
In power system, DSTATCOM can be used to ensure that the current drawn from the distribution bus is balanced and sinusoidal in distribution system. The power quality problems mainly arise. DSTATCOM is a shunt compensation device which is generally used to solve power quality problems in distribution systems. it causes the degradation of the entire system performance. The control strategy of DSTATCOM plays an important role to meet the objectives. A novel adaptive control strategy for the DSTATCOM is based on Hybrid Genetic Algorithm was presented to tune the coefficient of PID. With this control method, the compensator can stabilize the PCC voltage around a prescribed value. A distributes power system is developed in MATLAB environment, the validity of the method proposed is verified.
