摘　　要：根据电网安全校正策略的某优化模型对电力系统进行了合理的简化,将发电机和负荷的参数调整问题转化为建立、求解非线性的连续和二元混合规划问题。模型根据设置的复杂约束条件和合理的目标函数,通过求解数学模型得出合理有效的安全校正方案,并进行在线安全校正,在短时间内恢复系统正常运行,避免连锁故障的发生,有较好的安全性和合理性。An optimization model of power grid security correction strategy is proposed,in which the electric power system is simplified and the adjustment of the generator and load parameters is transformed as solving nonlinear consecutive and binary mixed programming problems.By setting complex constraints and a reasonable objective function,the mathematical model is solved to get a reasonable and effective security correction strategy.Then,online security correction is carried out to restore the normal operation of the power system quickly and to avoid the occurrence of cascading faults.It shows that the proposed model is of good safety and rationality.
