摘要
运用模型仿真和程序设计的方法研究自并励励磁系统的滞后特性,分析运行工况各参数对励磁系统滞后特性的影响。根据华北某电厂经过时域仿真校验的实测数据利用Simulink仿真进行频域分析,分析了不同系统参数对励磁系统滞后特性的影响,并得到最大工况和最小工况下的系统滞后特性。根据不同工况的滞后特性对PSS参数进行进一步整定,使其补偿特性都满足工程要求。
Applying model simulation and program design, the hysteretic characteristics of the bus fed static excitation system are introduced and the influence of operational parameters on excitation system hysteretic characteristics with single machine infi- nite bus (SMIB) model is analyzed. According to the field-test data which has been verified by time domain simulation, the influence of different system parameters on excitation system hys- teretic characteristics by Matlab/Simulink in frequency domain is also researched and the hysteretic characteristics of maximum and minimum operational condition is got. Responding to the hysteretic characteristics of different operational conditions, the PSS parameters have been tuned in order to make the compensatating characteristics meet the practical requirement.
