摘要
根据河源电厂1000 MW火电机组低压加热器疏水系统的特点,为解决低加水位调节品质差,多次导致低加解列和低加疏水泵跳闸等问题,通过引入低加疏水泵变频控制策略,优化了8#低加水位控制回路。实践结果表明:优化后,低加水位的调节品质得到明显改善,低加疏水泵的耗电量平均降低了36%,减少了设备磨损,提高了机组的稳定性与经济性。
In order to improve the poor quality of water level regulation of low pressure heater,which have repeatedly led to low pressure heater disconnection and its drainage pump tripping,the water level control loop of the 8#low pressure heater is optimized by introducing a variable frequency control strategy for the low pressure heater pump according to the characteristics of the low-pressure heater drainage system of the 1,000 MW thermal power unit in Heyuan Power Plant.The practical results show that after optimization,the regulation quality of the water level has been significantly improved,the average power consumption of the low-pressure heater drainage pump has decreased by 36%,equipment wear has been reduced,and the stability and economy of the unit have been enhanced.
