摘要
本文应用总体评价法和系统仿真分析了哈汽厂２００ＭＷ机组甩负荷后带厂用电的动态性能。研究表明，此时系统的动态性能虽有所改善，但克服非线性因素引起的振荡和改善系统稳定性仍不可忽视。此外，为了避免在甩负荷时转速形成明显的第二峰，电超速保护装置的推持时间宜取较小值。
In this paper, a brief analysis of dumping dynamics of 200MW turbo generator while it remains a little load for power plant itself has been performed in both stability and dynamic overspeed. The application of the Method of General Estimation and the system simulation shows that the dynamic behavior of the control system is improved ,but oscillations owing to nonliear factors can not be ignored. Finally, for avoidance too large the second peak of the overspeed, to reduce the time constant of OPC is recommended.
