摘要

无功功率对电力系统的可靠性起着重要的作用，它与系统电压稳定和电压崩溃密切相关。然而，在传统的电力可靠性评估中，与无功有关的可靠性问题很少得到重视。本文分别从有功功率和无功功率的角度对电力系统可靠性进行了研究。电力系统的可靠性评估主要考虑有功功率和无功功率不足以及系统故障引起的电压扰动。为了确定有功功率和无功功率对系统可靠性的影响，找到缓解网络违例的最佳方法，采用了一种针对过去突发事件的三级减载技术。

Adequacy evaluation of active and reactive power in power systems

Reactive power plays an important role in power system reliability as it is closely related to system voltage stability and voltage collapse.However,the reactive power related reliability issues are seldom emphasized in conventional power reliability evaluation.This paper studies the power system reliability from the perspective of active and reactive power, respectively.Active and reactive power inadequacy and the associated voltage perturbation due to system failure are considered in reliability evaluation of power systems.A three-stage load shedding technique for past contingencies are implemented to determine the influence of active and reactive power on system reliability and to find an optimal way to relieve network violation.

期刊介绍： Founded in 1977, Power System Automation is a well-known journal in the discipline of electrical engineering in China. At present, it has been issued to all provinces, cities, autonomous regions, Hong Kong, Macao and Taiwan, and abroad to dozens of countries in North America, Europe and Asia-Pacific region, with a large number of readers at home and abroad. Power System Automation takes “based on China, facing the world, seeking truth and innovation, promoting scientific and technological progress in the field of electric power and energy” as the purpose of the journal, mainly for the professional and technical personnel, teachers and students engaged in scientific research, design, operation, testing, manufacturing, management and marketing in the electric power industry and higher education institutions as well as electric power users, and focuses on hotspots of the industry's development and the It focuses on the hot and difficult issues of the industry. It focuses on the hot and difficult issues of the industry, both academic and forward-looking, practical and oriented, and at the same time emphasizes and encourages technical exchanges of experiences, improvements and innovations from the front line of scientific research and production.
