【摘要】 电力系统全停电后的黑启动恢复问题是电力系统安全防御的重要课题,科学合理的黑启动方案对于实现系统全停后的快速恢复意义重大。该文提出了一种基于数据包络分析模型的电力系统黑启动方案相对有效性的评估方法。该方法将黑启动方案的技术校验结果纳入评估体系,并依据实际的输入、输出指标值做出方案是否有效的客观评价。针对某实际电网的应用实例证明了该方法将为调度运行人员进行黑启动恢复提供更加科学的决策参考。更多还原

【Abstract】 Restoration of a power system after a complete blackout is a very important issue to the safety of the power system. Reasonable black-start plans are necessary to restore the power system as soon as possible. Based on data envelopment analysis, a new method for assessing black-start plans is proposed in this paper. Technical verification of the plans is considered in the assessment process. Whether a plan is effective is defined by its input and output index values entirely. The application to a practical power system verifies that the method could provide dispatchers more comprehensive and objective decision references.更多还原
