针对某煤矿10 kV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10 kV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。

According to a coal mining enterprise which urgently needs to analyze how SVC device influences the sta-bility of the whole system, an SVC stable analytic method has been proposed based on the stability boundary theory of semi-tensor product.The semi-tensor product stability boundary theory is applied to the 10kV distribution network of a coal mine which has already installed SVC devices.According to the actual situations, the system stability margin index has been analyzed, and a mathematical model has been established which will judge the stability of the system.Besides, Matlab software has been adopted to simulate the whole system.Finally, how the SVC devices influ-ence the system voltage stability has been obtained.This plan will not only simplify the calculation, but also 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.
