摘要

电网频率和发电机转速是发电机转子角的微分量，因此通过控制转子角即可实现有功跟踪和频率控制。文中阐述了实施有差转子角控制后负荷变化时，多个发电机无需调度指令自发调整出力，共同分担负荷变化并维持频率恒定的机理。随后给出了负荷变化引起的调整结束进入稳态后出力变化量和角度变化量的关系，并进一步给出了实施有差转子角控制后可用的潮流算法。分析表明，通过简单修正牛顿-拉夫逊法即可将其用于有差转子角控制的潮流计算，计算结果可以和仿真结果很好地吻合。该算法可以在实施转子角控制后用于静态安全分析或状态估计计算。

Abstract

The frequency of power system and the rotational speed of generator are the derivative of generator rotor angle

so they can be controlled by the generator rotor angle. This paper describes the mechanism that

after rotor angle droop control is implemented

generators can autonomously adjust the power output to share load variations and restore frequency without dispatching center intervention. Then the relationship between the power output variation and the rotor angle variation after the transient process(caused by load change)ends is provided. Further

the power flow calculation method that can be used after the implementation of rotor angle droop control is given. The analysis shows that

after slight modification

the Newton-Raphson method can also be used as a power flow calculation method under the rotor angle droop control. The calculation results can be well matched with the simulation results. The method can be used for static safety analysis or state estimation calculation after implementing the rotor angle droop control.
