摘要:

在新型电力系统背景下,安全稳定运行对主控型系统安全稳定服务有更大程度的依赖。服务响应的事前-事后全过程评估是实现主控型系统安全稳定服务质量有效管控不可或缺的技术基础。针对主控型系统安全服务质量评估的共性问题,分析了主控型系统安全稳定服务的特征、质量评估的内涵及要素,包括服务响应前的服务装备质量评估和服务资源质量评估,以及服务响应后的服务响应质量评估;阐述了系统安全稳定服务质量评估中的评估依据(服务质量特性预期)、评估指标体系、评估方法和基础数据要求;初步提出了包括收集厂站基础数据、确定质量要素特性评估准则、质量要素特性指标评估、稳定服务质量指标评估和稳定服务质量评级等环节的在线评估框架。对众多类型的系统安全稳定服务实现关键环节完整和功能信息齐全的质量评估,具有普适性的参考价值。

Abstract:

In the context of new power system, the safe and stable operation of power system is more dependent on the control-based system security and stability service. The ex-post and ex-ante entire-process evaluation of service response is an essential technical support to realize the effective management and control of the control-based system security and stability service quality. To address the common problems in assessing the control-based system security and stability service quality, this paper analyzes the characteristics of the control-based system security and stability service, and determines the connotation and factors for assessing the control-based system security and stability service quality, including service equipment quality and service resource quality before service response, as well as the service response quality after service response. The criteria, index system, methodology and basic data for assessing the control-based system security and stability service quality are described. Finally, an online assessment framework for control-based system security and stability service quality is proposed, including collecting basic data from power plants and substations, determining the assessment criteria and indexes for quality elements, evaluating the indexes and levels for stability services quality, which has universal applicability to the quality assessment of various control-based system security and stability services, including entire key links and complete functional information.
