摘要
随着电网规模越来越大,电力系统区域间存在多种振荡模式。电力系统稳定器(PSS)是解决低频振荡的有效措施之一,但对区域间振荡抑制能力明显不足,宽频段电力系统稳定器可以解决这种不足,同时对发电机组调频系统产生的超低频振荡也具有抑制作用,笔者对宽频段的电力系统稳定器传递函数模型进行了介绍,对宽频段电力系统稳定器的阻尼效果进行了仿真,并在国内首次完成现场测试,希望对其在工程的应用具有借鉴意义。
With the development of power grid scale, there many mode of low frequency oscillation exists in local power grid. Power system stabilizer （PSS） is one of the effective measures to solve the low frequency oscillation, but it has some shortcomings to solves local oscillation, which is solved by the wild band power system stabilize, at the same time wild power system stabilizer has the influence on the super low frequency by the adjusting frequency of generator. The author introduce the transfer function model of the wild band power system stabilizer, the simulation results gives the damping of power fluctuation and the first field test effect in domestic, We hope it has reference significance in engineering application.
