| 摘 要： | 电力系统稳定器(PSS)的参数整定正确与否关系到对低频振荡的抑制效果.提出了一整套关于发电机励磁系统PSS的参数优化设计、现场整定试验和仿真校核计算的方法.该方法基于电力系统分析软件PSD的BPA潮流和暂态稳定及SSAP小干扰稳定程序.采用实际电网和各设备详细模型,特别是准确的励磁系统模型,通过频域和时域分析法,并结合低频带相位补偿法设计并优化配置PSS参数;再通过PSS现场整定试验,即无补偿、有补偿频率响应特性及抗扰动试验再次优化并确定参数;最后采用典型方式下的潮流稳定数据进行建模和仿真校核计算.以600 MW机组为例,证明该方法对系统振荡模式分析和PSS设计的准确性和有效性.

| Abstract: | The parameter setting of PSS(Power System Stabilizer) is related to the damping effect of low frequency oscillation. Methods of optimal parameter design,field adjustment test and simulation verification is presented for PSS of generator excitation system,which is based on the power system analysis programs of PSD regarding BPA power flow, transient stability and SSAP small disturbance. The actual power system and detailed equipment models,in particular a precise excitation system model,are applied and the f... |
