摘　　要：通过数值模拟和实际机组实验,对DEH系统实现一次调频、二次调频的问题进行了研究;配合超速控制硬件,完成了机组在甩大电网负荷、带孤立电网的功率和频率调节,证明这种孤立电网的控制方式是恢复大电网正常运行,解决黑启动问题的有效途径。By digital simulation and experiments on actual power unit, problems occurring in primary and secondary, frequency modulation processes for DEH system are studied. With overspeed control hardware, frequency modulation and power adjustment were completed for the unit under heavy load rejection and island power grid operation conditions. This proves the control method to be effective in putting large power grids return to normal operation as well as solving the ＂black start-up＂ problem.
