摘要：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。

Abstract：According to a coal mining enterprise who which urgently needs to analyze how SVC device influences the stability of the whole system, this paper proposes an SVC stable analytic method has been proposed which is based on the stability boundary theory of semi-tensor product. Apply tThe semi-tensor product stability boundary theory is applied to the athe coal mine 10kV distribution network of a coal mine which has already installed SVC devices. According to the actual situations, analyze the system stability margin index has been analyzed, and establish a mathematical model has been established which will judges the stability of the system, . besides Besides, use the Matlab software has been adopted to simulate the whole system, . finally Finally, obtain how the SVC devices influence the system voltage stability has been obtained. This plan will not only simplifies simplify 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.
Key words：power quality, semi-tensor product, stability of system, stability index
