在对嘉峪关宏晟电热公司2×300 MW机组控制策略的优化完善基础上，进行了自动发电控制（AGC）功能静态和动态试验测试，并对试验数据做了对比分析处理，确定了机组AGC功能的各项指标，最终达到电网要求并正常投入使用，提高了该机组的安全性、稳定性和经济性，为随后新建4×350 MW机组提供参考依据。%On the basis of control strategy optimization of the 2í300 MW generating u-nit of Jiayuguan Hongsheng Electrothermal Co., Ltd., static and dynamic tests of the function of automatic generation control (AGC) were carried out, then the test data were compared and analyzed and index of the AGC function were determined, which met the requirements of the public power grid. The system has been normally put into operation, which has improved the safety, stability and economy of the generators and provides some reference for construction of new 4í350 MW units.
