| 摘要: |
| 综述了现代电力系统恢复控制的任务、主要问题以及解决方法。从宏观角度将恢复控制划分为恢复计划和恢复培训、有功平衡与频率控制、无功平衡与电压控制和继电保护以及安全自动装置的配合4个主要问题。恢复计划的制定是一个复杂的优化问题,一般可离线预计划,并采用人工智能技术和最优化方法相结合,予以解决。对于有功平衡与频率控制问题,要考虑电源恢复和负荷恢复2个方面。电源恢复是一个动态规划问题,要求在满足各种约束条件下,使系统的发电量最大;而负荷恢复目前是研究热点,其要求和电源恢复同步进行,满足频率约束、网络约束并考虑社会经济效益。主要方法有遗传算法、蚁群算法以及一些近似算法。对于无功平衡与电压控制问题,综述了持续工频过电压、操作过电压和谐波过电压的产生原因、控制手段以及目前的预测和控制方法,主要包括基于灵敏度分析、概率统计以及神经网络的方法。最后,综述了系统恢复不同阶段中继电保护以及安全自动装置的配合的主要问题和处理方法。 |

| Abstract: |
| An overview of power system restoration control is presented,including its tasks,main issues and solutions.The power system restoration control can be divided into four aspects:recovery scheduling and training,active power balance and frequency control,reactive power balance and voltage control,and coordination of relay protection and automatic security equipment.Recovery scheduling is a complicated optimization problem,which can be offline solved using both optimization algorithm and artificial intelligence technology.Active power balance and frequency control should consider both generation and load recoveries.The former is a dynamic planning for the maximum power energy during recovery with all operating constrains satisfied,while the latter takes place at the same time of generation recovery with frequency and network constrains satisfied and load priority considered.It includes genetic algorithm,ant colony optimization method and other approximation algorithms.In reactive power balance and voltage control,the causes of sustained power frequency over-voltage,switching over-voltage and harmonic over-voltage are discussed,and their prediction and control methods are summarized,including sensitivity analysis,probability and statistics,neural network,etc.In coordination of relay protection and automatic security equipment,its key points and solutions in different restoration stages are discussed. |
