摘要
一次调频对电网稳定性至关重要,因此电网要求并网机组需具备一次调频能力。某核电厂汽轮发电机采用负荷闭环控制和压力控制两种控制模式共同进行汽轮机发电功率控制,试验发现当汽轮机处于负荷闭环控制模式下,若一次调频幅度超过3%时,将引起汽轮机快速甩负荷至零,并跳机。本文对此问题进行分析并提出修改方案。
As primary frequency control is essential to the stable of grid,so the power plant which connected to the grid should have the capability of primary frequency control.it is found that during primary frequency control test of one nuclear power plant,if the amplitude of primary frequency is over 3 %,the turbine of the nuclear power plant will be tripped.This paper analyze the reason and give the solution.
