| Transmission system reliability management is a new content generated along with the deepening development of reliability management. In order to effectively analyze the reliability level of power grid, based on the reliability of power transmission and transformation equipment management, through the combined model of power outage, outage events evaluation of comprehensive statistics, and gradually formed a power transmission system reliability. In2009, the China State Grid Corp officially launched the pilot work of power transmission system reliability statistics, the short-term goal is to complete the transmission system of data collection, statistics and analysis of influence factors, system reliability, changes and improvements, the long-term goal is to network planning, design, operation and management to provide the required information to optimize the allocation of resources.Transmission system reliability management for power grid reliability is to loop function as the target of. System reliability management division and the statistical circuit as the foundation, take the computer as the tool, through the analysis of the indicators, quantitative description of the different sections of the state power grid. Transmission system reliability in transmission and distribution facilities based on the reliability, introducing "loop" concept, reflecting the power transmission system under specified conditions and a specified time to complete the functions of. Transmission system reliability management through the division of the different functional circuit, method of quantitative statistics reflect the different sections of the state power grid.This paper first of all domestic and international electric power reliability management for analysis and research, combined with China’s national conditions and transmission reliability management features, analyzes the management status, transmission reliability management of the current problems, and puts forward the improvement direction. This paper presents the reliability analysis method of management model and statistical power transmission system, and the research.The basic data transmission system reliability statistics mainly comes from the reliability of power transmission and transformation equipment, including not only the thirteen kinds of facilities in reliability statistics include, relay protection, automatic devices, telecontrol, communication equipment and ancillary facilities two belong to the system reliability. |
