摘要：在电力传输过程中，由于大量无功功率的存在，不可避免地导致线路损耗的增加，给用电设备安全运行带来了隐患。

Absrtact: a mass of reactive power exists in electric power transmission course, accordingly the wasting of circuitry increases and the electrical equipment safe have brought hidden trouble.

当无功功率不平衡时，将会导致系统电压降低、电能质量下降、功率因数降低、线损增加等问题。

When reactive power is unbalance, it will cause some problems, such as lower voltage, worsen voltage quality, lower power factor and increase line loss.

通过对单机。动态负荷模型添加无功功率动态补偿装置，可以改变原系统的分岔点，增加了负荷极限，从而提高了系统电压稳定性。

Through the single-dynamic load model dynamic reactive power compensation device can change the original system bifurcation point, increase the load limits and improve the system voltage stability.
