Optimization on primary frequency control for a supercritical 350MW unit
摘要
由于海南电网容量较小
使得机组的一次调频存在动作频繁
单方向动作的时间长、幅度大的特点
且在运行方式上存在联网和孤网2种运行模式
一次调频控制相对较复杂。对此
在分析海南电网运行特点的基础上
对华能东方电厂超临界4×350MW机组的一次调频控制策略进行优化
以解决频繁的小幅度一次调频动作的问题
提高一次调频的控制品质。同时
对机组协调控制进行相应的优化
在保证一次调频控制品质的基础上
提高了机组运行的安全性、稳定性。
Abstract
Small capacity of Hainan power grid causes several problems
like frequent primary frequency regulation of the units
long time and large amplitude of single direction movement during primary frequency regulation
and others.Furthermore
as the power grid has two operation modes(networking and isolated grid)
the primary frequency control is relatively complex.Therefore
on the basis of analyzing the operation characteristics of Hainan power grid
the primary frequency control strategy of a 350 MW unit was optimized
to solve the frequent small amplitude primary frequency regulation problem and improve control quality of the primary frequency control.In addition
corresponding optimization on coordinated control system was also conducted to enhance the safety and stability of the unit operation
on the premise of ensuring the primary frequency control.
