摘要
华北电网《两个细则》对发电机组自动发电控制(AGC)调节性能提出了具体要求。针对某F级二拖一燃气-蒸汽联合循环机组AGC负荷变化速率和负荷响应速度低的问题,在汽轮机功率控制回路增加变参数比例-积分-微分(PID)控制并在AGC功率和速率限制回路采用阈值法,提高了汽轮机组负荷响应速度和负荷变化速率。在保证机组安全稳定运行的前提下,满足了电网AGC考核的要求。
Specific requirements to regulation performance of automatic generation control( AGC) of power unit are proposed by the'two rules'of North China Grid Company Limited. For the problems of low load change rate and low load response speed of AGC existed in a certain F class two-on-one gas-steam combined circulating generation unit,a proportion integration differentiation( PID) control of variable parameters is added in the power control circuit of steam turbine,and a threshold method is adopted in the power and speed limiting circuit of AGC,which improved the load change rate and load response speed of steam turbine unit. After that,it meets the examination requirements of AGC under the premise of guarantee the safe and stable operation of unit.
