摘要
从流形变换的角度,提出一个新的电力系统故障后临界失稳模式预测的计算方法;推导了电力系统的临界失稳模式预测的公式;分析了影响失稳模式的因素;用新英格兰系统验证了预测临界失稳模式的公式的正确性,计算结果表明用该公式能准确预测电力系统的临界失稳模式。预测公式采用了三阶非线性变换,具有较高的计算精度。
A new approach is proposed in this paper to predict the critical unstable modes of a disturbed power system based on manifolds trans-
formations; the prediction formula of critical unstable modes of the disturbed power system is derived; the factors that affect the unstable modes
are analyzed; the correctness of the prediction formula is verified through the calculation example of New England electric power system. The
results show that the critical unstable modes of a disturbed power system are correctly predicted by this prediction formula. A three order
nonlinear transformation is adopted in the prediction formula and the precision is sufficient.
