构建电力可靠性管理新格局 推动电力可靠性工作高质量发展

Core Insights - The article highlights the significant achievements in power reliability management in China over the past 40 years, emphasizing its role in ensuring the safe and stable operation of the power system and supporting economic and social development [2][3]. Group 1: Historical Achievements - The establishment of the Power Reliability Management Center in 1985 marked the beginning of specialized management in China's power reliability, leading to a comprehensive management system that includes government leadership and industry service [1][2]. - Over 3,000 power companies are now included in reliability statistics, with more than 6,000 professionals dedicated to reliability management and information statistics [2]. Group 2: Improvements in Reliability Metrics - The reliability level of China's power system has significantly improved, with unplanned outages for coal and hydro power units decreasing by over 93% compared to 40 years ago [3]. - Key equipment such as transformers and circuit breakers now have an equivalent availability factor exceeding 99% [3]. Group 3: Enhancements in User Experience - The average outage time for urban users has decreased by 94.55 hours since 1991, with major cities achieving average outage times of less than one hour [4]. - Rural users have seen an 83.67-hour reduction in average outage time since 2004, addressing issues like frequent outages and low voltage [4]. Group 4: Future Challenges and Requirements - The transition to a new energy system requires innovative reliability management methods to address the complexities introduced by renewable energy sources and electric vehicles [5][6]. - There is a need for improved reliability statistics that encompass low-voltage users and renewable energy sources, as current data only covers a fraction of installed capacity [7]. Group 5: Strategic Directions for Development - The focus is on enhancing the reliability management framework to support high-quality economic development and meet the increasing expectations of the public regarding power reliability [8][10]. - The establishment of a professional education system for reliability management is essential to improve the overall competency in the sector [11].
