基于半张量积稳定域理论的SVC系统稳定性分析

针对某煤矿10kV配电网络亟需分析SVC装置对系统稳定性影响的实际需要。提出了一种基于半张量积稳定域边界理论的SVC系统稳定分析方法。将半张量积稳定域边界理论应用于装设SVC装置的某煤矿10kV配电网络中,根据实际工况对系统进行稳定裕度指标分析,建立可判断系统稳定性的数学模型,并利用Matlab对系统模型进行仿真,得到SVC装置对系统电压稳定性的影响规律。该方案既简化了计算又可以根据稳定指标判断系统的稳定程度,对系统稳定性的判断有很高的参考价值。

Analysis of SVC System Stability Based on Semi-Tensor Product Steady Boundary Theory

According to a coal mining enterprise who urgent needs analyze how SVC device influences the stability of whole system, this paper proposes a SVC stable analytic method which is based on stability boundary theory of semi-tensor product. Apply the semi-tensor product stability boundary theory to the a coal mine 10kV distribution network which installed SVC devices. According to the actual situation, analyze the system stability margin index, establish a mathematical model which judges the stability of the system, besides use the Matlab software to simulate the whole system, finally obtain how SVC devices influence system voltage stability. This plan not only simplifies the calculation, but also can judge the stable degree of system based on the stability index. It has a strong reference value which can judge the stability of the system.
