摘要(Abstract):
为适应大电网对机组快速响应提出的更高要求,发电机组在锅炉跟随协调方式下应能快速响应电网负荷并保证机组压力及各运行参数的稳定。这就要求机组在自动发电量控制(AGC)调节精度上达到最大程度的提升,以满足电网的需要。针对300 MW机组的特点,对协调控制策略进行优化改进,保证机组负荷的快速响应和稳定运行。
To adapt to the grid′s higher requirements for fast response of units,generator units should respond to grid load fast in boiler follow(BF) mode and ensure the stability of unit pressure and all the operating parameters.That requires units to achieve greatest improvement on adjustment accuracy of automatic generation control(AGC) to meet the needs of grid.The optimization of coordination control strategy is performed according to the characteristics of 300 MW units.Meanwhile the fast response to unit load and stable operation are ensured.
