摘要
结合时域仿真 ,提出了多机系统中单机加速面积、减速面积计算方法、临界机组群单机等面积定则第一摇摆稳定判据、稳定裕度计算方法等。并提出了加速面积、减速面积、减速功率 (稳定裕度 )对网络节点有功、无功及变压器变比的灵敏度分析方法。临界机组群单机等面积定则第一摇摆稳定判据与时域仿真角度准则精度相同 ,但具有数值积分时间短的优点 ;暂态稳定裕度灵敏度能用于暂稳控制装置安装地点的选择、安全校正再调度及系统稳定裕度约束和在线稳定监视。
Based on the time domain simulation, the calculation methods for single machine acceleration area and deceleration area are proposed. The critical machine group single machine equal area criterion is developed. The stable margin is defined. The proposed critical machine group single machine equal area criterion needs less computation time compared with the traditional time domain simulation. The sensitivity of stability margin with respect to node active and reactive power is derived, they can be used in the location selection of transient stability control devices, stability margin constraint of security based economic dispatch and online stability monitoring. Practical system analysis is presented.
