摘　　要：随着发电厂辅助服务及并网运行实施细则考核,并网发电厂积极响应,不断开展设备检查整改工作,通过试验、优化运行调整和设备改进,提高机组运行指标满足调度要求,本文介绍了容易忽视的量值传递误差,通过试验查找产生误差的原因,通过简单的参数修正和设备改进即减少了0.5%的量值传递误差又减少了量值传递延时,提高了自动发电控制能力,最终提高了机组运行的经济性。该方案对并网发电公司提高AGC调节能力有一定的参考价值。As the power plant auxiliary services and the detailed rules for the implementation of the parallel operation developing, power plant kept continuously active response. Through the test, the rectification adjusting and optimizing operation, equipment unit operation indexes meet scheduling requirements. This article introduces easily neglected value transmit.in error. Through test for errors, simple parameters and equipment improvement, it reduced not only the value transmit.in 0.5% error but also the delaying. Thus it improved the dissemination of automatic generation control ability, and finally the efficiency of the unit operation was raised. The scheme for the generation company improving AGC adjustment ability has certain reference value.
