摘　　要：为解决区域电网绿色能源的平稳外送问题,提出由燃气-蒸汽联合循环机组与区域内多个风电场共同组成风-燃互补联合发电系统的控制方案。首先建立考虑转速控制、温度控制和燃料控制等的燃机综合模型,由动态响应曲线可知其响应时间短、调节速度快,具备补偿风功率波动的能力。在此基础上提出风-燃互补的双层复合控制策略,计划调度层通过风功率预测得到燃机基准功率,实时优化层综合考虑机组耐用度和控制效果,实时补偿风功率波动和频率偏差,从而使联络线功率按计划运行并维持系统频率稳定。最后,以中国某海岛电网为应用案例搭建RTDS全岛仿真平台,验证所提控制策略的有效性。In order to solve the problem of smooth transmission of green energy through regional scheme of wind-gas combined system for complementary power generation was proposed, which steam combined cycle unit and multiple wind farms in the region. At first, the integrated model power grid, a control was composed of gas - considering the speed control, the temperature control and the fuel control for the gas turbine was developed. It could be seen from the dynamic response curves that the gas turbine had short response time and fast ramp rate so that it could be used to compensate the fluctuations of the wind power. Then the double layer composite control scheme of the wind-gas combined system was proposed, the plan and scheduling layer got benchmark power of gas turbine through wind power forecast, real-time optimization layer considered synthetically endurance and control effect of gas turbine, compensating real time undulation of wind power and frequency deviations so that made the liaison-line power operate according to the plan and maintain the stability of system frequency. At last, an RTDS simulation platform was built based on the actual data of certain island in China, and verified the effectiveness of the proposed control scheme.
