【摘要】：人们日常生活对于电的依赖,伴随着社会经济的不断向前,呈现出越来越高的态势,对于停电的忍耐度越来越低,甚乎于“零容忍”。这就对供电企业提出了越来越高的要求,既要稳定供电,又要提高电能质量。“多供电、供好电,提高供电可靠性是关键”就成为电力企业的核心竞争力。同时,随着新一轮电改的开始,售电侧的逐步开放,传统的供电企业要立足于市场,就更要确保可靠供电。作为评价供电企业服务质量水平的核心标准,供电可靠性反映了电力企业对用户电能需求的满足程度,这就为供电企业改革创新指明了方向。总而言之,国家的繁荣,经济的持续、健康、快速发展,社会的进步,都离不开电力的可靠供应。供电可靠性的提高,不是简单的加大投资力度,而是一项十分复杂、艰巨的综合性工作。必须从网架完善,运行维护,管理创新等多方面进行总结和改进。本文首先阐述了国内外关于供电可靠性的研究现状和相关理论,指出了电力企业供电可靠性的研究首先应该建立系统的概念,至少以一个自然年为统计分析的周期,才能保证数据具有普遍性和参考性。但同时,因为在电力系统中,绝大多数的用户是通过配电系统来获取电能的,系统各个环节的问题,最终都是通过配电系统反馈至用户侧,故可以配电系统为切入点来做可靠性指标的统计及分析。然后,介绍了湛江市及湛江电网的概况以及供电可靠性现状,全面分析了湛江地区2014年供电可靠性运行数据,通过对预安排停电及故障停电两个维度的可靠性指标的剖析,找出了10kV配电网设施计划施工及台风等10个影响湛江地区供电可靠性的主要因素,明确了从减少停电次数和降低停电影响两个方面来设计提升策略。最后,分别从完善电网结构、优化电网运行方式、提升基础管理水平、推进技术进步四个维度,提出了提升策略和具体措施。
[Abstract]:With the development of society and economy, people's daily life depends on electricity, and their tolerance to power outage is becoming lower and lower than "zero tolerance". This puts forward more and more demands on power supply enterprises. It is not only necessary to stabilize power supply, but also to improve power quality. "multiple power supply, good power supply, and improving power supply reliability" become the core competitiveness of power supply enterprises. At the same time, with the beginning of a new round of electricity reform, the power sale side will gradually open up. If traditional power supply enterprises want to base themselves on the market, they should ensure reliable power supply. As the core standard of evaluating the service quality level of power supply enterprises, the reliability of power supply reflects the degree of satisfaction of power enterprises to users' power demand. All in all, the prosperity of the country, the sustained, healthy, rapid development of the economy and the progress of society cannot be separated from the reliable supply of electricity and the improvement of the reliability of power supply. It is not a simple increase in investment, but a very complex and arduous comprehensive work. We must improve the grid structure, run and maintain it. Firstly, this paper expounds the current research situation and related theories of power supply reliability at home and abroad, and points out that the research of power supply reliability in electric power enterprises should first establish the concept of system. At least one natural year is taken as the period of statistical analysis to ensure that the data is universal and referential. But at the same time, because in the power system, the vast majority of users obtain electricity through the distribution system, the problems in all aspects of the system. In the end, all of them are fed back to the user side through the distribution system, so the distribution system can be used as the breakthrough point to make statistics and analysis of the reliability index. Then, the general situation of Zhanjiang and Zhanjiang power grid and the present situation of the power supply reliability are introduced. The reliability operation data of power supply in Zhanjiang area in 2014 are analyzed, and the reliability indexes of two dimensions of pre-arranged power outage and fault blackout are analyzed. This paper finds out the main factors that affect the reliability of power supply in Zhanjiang area, such as the planned construction of 10kV distribution network facilities and typhoon, and clearly designs the promotion strategy from two aspects: reducing the number of power outages and reducing the impact of power outages. From four dimensions of perfecting the power network structure, optimizing the power grid operation mode, improving the basic management level and promoting the technological progress, this paper puts forward the promotion strategy and concrete measures.
