摘　　要：通过动模试验验证了转子角控制的可行性和转子角控制模式下的负荷跟踪机制的有效性,试验表明,现有的测量精度和控制技术完全可以实现定转子角控制。试验还表明,实施转子角控制并不意味着本地发电机要独自承担本地负荷,在负荷快速增长或者大扰动发生时,配置传统调速器和配置转子角控制器的发电机都会参与调节,调整结束后负荷增量会由多个定角度机组共同分担。此外,如果运行于定转子角模式的发电机到达出力上限,该发电机就会失去维持角度的能力,但相邻的发电机可在负荷增长时提供支援,因此系统频率仍可维持不变。The feasibility of rotor angle control and the effectiveness of load balancing mechanism in the rotor angle control mode are verified by experiments and the experimental results show that,the present measurement accuracy and control technology can completely realize the rotor angle control;the local load is not born by the local generator alone in the rotor angle control mode：when load increases quickly or large disturbance occurs,the generators with speed governor or rotor angle controllor will all participate in the load adjustment and the load increment will be shared after the adjustment among multiple generators with constant rotor angle. The generator with constant rotor angle may lose the ability to maintain the rotor angle if its upper limit of power output is violated,but the adjacent generators will provide supports during the load growth to maintain the system frequency.
