Phasor Measurements in the Western Electric Power System

Abstract: This paper presents the use of phasor measurement units (PMUs) in the Western Electric Coordinating Council (WECC) has been very successful. Phasor data recorded during the Aug. 10, 1996 blackout showed the phase difference growing as the system weakened well before system separation. It also showed clearly the dynamic system behavior before and during the blackout. WAMS measurements, particularly phasor measurements, filled the need to see system behavior that other measurements did not cover. Phasor measurements are now widely dispersed in the WECC, most of the in real-time systems. More of these are being connected in wide-area networks to support continuing efforts to improve operations

Power network blackout arranging method and device

Abstract: The invention discloses power network blackout arranging method and device. The method comprises the following steps of: acquiring a blackout plan as well as topological information of main and distribution network equipment; acquiring a substation set and a distribution network bus set corresponding to blackout equipment according to blackout equipment information in the blackout plan and the topological information of the equipment; confirming power supply paths of each substation and each distribution network bus according to the substation set and the distribution network bus set; and remaking the blackout plan according to the power supply paths and set adjustment steps to obtain power network blackout arranging information. The method and the device can be used for obtaining the more optimized power network blackout arranging information, effectively reducing the frequency of repeated blackout, improving power supply efficiency, and providing a reference for reviewers to make a concrete blackout plan, thereby alleviating the influence of blackout on network power supply.

The Occurrence Reasons and Countermeasures to Power System Blackouts

Abstract: The modern power system of Russia covers huge territory from town Chita to the Kaliningrad region, from the North Caucasus to Kola peninsula, includes a number of the power associations in parallel working on interconnection lines, consists of many thousand power stations, transmission lines and transformers, and is connected with power systems of neighboring countries. They cannot work smoothly for a long time due to the aging of the equipment, the influence of natural environment and the mistaken duty personnel. Nevertheless, thousands of large power system disturbances are annually eliminated by relay protection and automatics devices, which are almost imperceptible for the consumer. But under certain conditions, there can be uncontrollable disturbance, so-called cascade failure with blackout. The special emergency control automatically counteract cascade failures, carrying out switching-off of less responsible consumers, and forming power system islanding into the separate isolated subsystems [1]. However, serious blackouts with catastrophic consequences for consumers and for the power system are still possible.

Analysis and Proposed Remedies for Power System Blackouts around the Globe

Abstract: Stable operation of power systems contributes towards the economic growth of developed and developing countries around the globe. Blackouts due to technical faults put the whole power system in danger. In this paper, a comprehensive analysis of power system blackouts, their root causes, and potential impacts on the economy of developed and developing countries around the globe is presented, along with possible approaches to avoid and resolve power system blackouts. The paper also proposes ways to avoid cascaded events in case of power system failure at a single point resulting in cascaded events and a complete blackout.
