宁夏电网并网机组以火电机组为主,网内电厂一次调频投入率低,一次调频能力差,无法满足宁夏电网安全稳定运行的要求。本文针对这一问题,通过对宁夏电网一次调频参数的模拟计算,最终得出适合宁夏电网的一次调频容量及死区的选取方法。结果表明:增加调速不等率为4.5%以及4%的机组参与调频的比例,可提高宁夏电网一次调频的能力。
寧夏電網併網機組以火電機組為主,網內電廠一次調頻投入率低,一次調頻能力差,無法滿足寧夏電網安全穩定運行的要求。本文針對這一問題,通過對寧夏電網一次調頻參數的模擬計算,最終得齣適閤寧夏電網的一次調頻容量及死區的選取方法。結果錶明:增加調速不等率為4.5%以及4%的機組參與調頻的比例,可提高寧夏電網一次調頻的能力。

Ningxia power grid integrated units are mostly coal-fired units. Primary frequency regulation of the power plant in the grid with low input and poor ability can not meet the demand of safe and steady operation of Ningxia power grid. Aiming at the above problems by simulated calculation of Ningxia power grid primary frequency regulation,obtain the suitable selective methods of Ningxia Power Grid primary frequency regulation capacity and dead zone. The results show that through adding unequal speed control rate as 4.5% and 4% units taking the proportion of frequency regulation can improve the capability of Ningxia power grid frequency regulation.
