【摘要】：供电可靠性是指配电网对用户持续供电的能力。它是电力可靠性管理的一项重要内容,直接反映了供电系统对用户的供电能力和服务质量,是一个供电企业技术装备水平和管理水平的综合体现。随着经济的迅速发展和人民生活水平的不断提高,电力用户对供电企业的要求已经不仅局限于满足负荷的增长需求,对供电可靠性和电能质量等也有了更高的要求。在智能电网快速发展阶段,构建以全面提升电网供电可靠性的电网规划方法研究,已经是电力部门急需解决的重要课题。本文主要研究配电网供电可靠性规划方法,形成了一套系统的配电网可靠性评估与规划方法。以该方法对太原迎泽区进行可靠性规划,可靠性指标提升效果明显,验证了该方法的有效性和科学性。本文的主要的研究成果及具体的内容如下： (1)确定配电网可靠性规划研究的方法,并对研究步骤进行详细说明。首先,系统分析供电可靠性现状指标及各影响因素之间的关联性,具体分析各因素对可靠性指标的影响程度,构建完整系统的影响因素体系,并依此挖掘现状可靠性薄弱环节；其次,制定科学合理的可靠性规划目标；最后提出了能同时保证计算速度与精度的可靠性计算算方法,依据可靠性薄弱环节提出一系列提升措施,实现投资效益比最优的规划优选方案。 (2)对于研究方法中的理论进行详细阐述,指导研究顺利开展。包括供电可靠性影响因素体系的建立与分析,研究供电可靠性目标及提升措施、配电网可靠性计算与评估研究、可靠性规划方案优选方法。 (3)利用上述配电网可靠性规划研究的方法对太原市迎泽区进行可靠性规划,验证该方法的有效性和科学性。
[Abstract]:Power supply reliability refers to the ability of distribution network to supply power continuously to users. It is an important content of power reliability management and directly reflects the power supply ability and service quality of power supply system to users. With the rapid development of economy and the continuous improvement of people's living standard, the demand of power supply enterprise is not only limited to meet the increasing demand of load, but also a comprehensive embodiment of the technical equipment level and management level of power supply enterprise. In the rapid development of smart grid, it is an important task for the power sector to construct a power network planning method to improve the reliability of power supply in an all-round way. In this paper, the power supply reliability planning method of distribution network is mainly studied, and a set of systematic reliability evaluation and planning method of distribution network is formed. The reliability planning of Yingze District of Taiyuan is carried out by this method, and the effect of improving reliability index is obvious. The main research results and specific contents of this paper are as follows:. 1) determine the research method of distribution network reliability planning, and explain the research steps in detail. First, systematically analyze the current status of power supply reliability indicators and the relationship between the various factors. Specific analysis of the impact of various factors on the reliability indicators, the construction of a complete system of impact factors system, and thus excavate the status quo of the weak link of reliability; secondly, the establishment of scientific and reasonable reliability planning goals; Finally, the reliability calculation method which can guarantee the calculation speed and precision at the same time is put forward. According to the weak link of reliability, a series of promotion measures are put forward to realize the optimal planning scheme of investment benefit ratio. 2) elaborate the theory of the research method in detail, guide the research to carry on smoothly, including the establishment and analysis of the power supply reliability influencing factor system, the research of the power supply reliability target and the promotion measure, the distribution network reliability calculation and the appraisal research, Reliability planning scheme optimization method. 3) the reliability planning of Yingze District of Taiyuan City is carried out by using the above methods of reliability planning of distribution network, and the validity and scientific nature of the method are verified.
