Abstract

This paper proposes a novel custom power device based on distribution static compensator (DSTATCOM) with PID controller driven by the unified error signal (UES) from a multi loop dynamic error controller scheme. Both DSTATCOM and UES are modified to meet the requirements for voltage stabilization, voltage waveform disturbance compensation and power factor improvement. A complete simulation model of the proposed system is developed in Matlab/Simulink Environment. The system is simulated with different control strategies under different operating conditions for comparison. The controllers and the control strategies are developed to have the novel DSTATCOM be operated for voltage stabilization, power factor improvement, energy losses reduction, power quality, and less harmonics distortion. The operational characteristics of a power system, supplying electrical power to hybrid loads consisting of linear and nonlinear and motorized loads, are investigated for better performance and higher power quality employing the proposed DSTATCOM and UES driven controllers.

一种新型DSTATCOM设备在配电网电能质量改善中的应用

本文提出了一种基于分布式静态补偿器(DSTATCOM)的新型自定义功率装置，该装置采用PID控制器，由多环动态误差控制方案的统一误差信号(UES)驱动。对DSTATCOM和UES进行了改进，以满足电压稳定、电压波形干扰补偿和功率因数改善的要求。在Matlab/Simulink环境下建立了系统的完整仿真模型。在不同工况下采用不同控制策略对系统进行仿真比较。开发了控制器和控制策略，使新型DSTATCOM能够稳定电压，改善功率因数，降低能量损耗，提高电能质量，减少谐波失真。采用DSTATCOM和UES驱动控制器，研究了电力系统的运行特性，为由线性、非线性和电动负载组成的混合负载供电，以获得更好的性能和更高的电能质量。
