【摘要】：电网企业具有资源优化配置平台的作用,随着我国电力消费比例、电网建设投资的日益增长,在国家节能减排工作中将占有更加重要的地位。研究表明,在电力系统各个环节中,配电网作为重损层,节能潜力最大。因此,利用节能技术差异化分析进行配电网节能潜力评估和节能规划方案制定,对于节能工作高效开展具有重要意义。针对配电网节能工作,不同的节能技术手段作用于同一配电网,同样的技术手段作用于不同运行状态下的配电网,其降损效果均存在差异性。因此只有认真分析电网设备、网架结构和电网运行之间的关系,才能掌握配电网能耗及其影响因子之间的关联性,从而制定出符合电网降损目标的节能技术方案,总结出全面的节能潜力分析方法使节能工作更具针对性。同时,配电网差异化节能是不仅满足单条线路不同节能技术手段的优化组合问题,又是满足节能经济性和运行条件约束下多条线路的配网多目标规划问题,只有通过建立合理的规划模型,才能从配电网的系统角度实现节能规划工作的指导意义。本文首先根据配电网设备和运行情况进行了损耗产生机理分析,并总结了对应的配电网节能技术手段,在此基础上梳理节能技术指标,形成节能改造技术准则,完成配电网节能分析体系的建立。其次,针对配电网节能潜力评估缺乏全面系统的定量研究问题,本文根据不同的电网数据采集情况,结合前推回代潮流计算和灰关联预测方法,分别形成了基于典型线路和基于区域配网的节能潜力评估方法,应用于不同配电网特点的节能潜力分析。针对目前配电网大多只进行单条线路不同节能技术手段优化组合,缺乏系统配电网的经济性和可靠性规划问题,本文在满足电网公司要求下的节能指标和成本约束的条件下,建立基于节能技术差异化分析的配电网分区的二层规划模型,完成了节能改造技术方案制定和节能投资优化分配。最终根据对功能需求的分析,搭建配电网节能辅助分析软件平台,结合算例说明,该软件可实现系统配电网的节能潜力评估和节能规划工作,具有良好的工程应用价值。
[Abstract]:With the power grid enterprise resource optimization configuration platform role, with the power consumption ratio in China, increasing investment in power grid construction, occupy a more important position in the national energy-saving emission reduction work in. The study shows that in all aspects of power system, distribution network as a heavy loss layer, the energy saving potential. Therefore, the use of energy-saving technology difference analysis of development of distribution network energy saving potential assessment and energy saving plan for energy conservation, is of great significance to carry out energy-saving work. According to the distribution network, energy saving technology different from the same distribution network, distribution network technology means the same in different operation conditions, the loss reduction effect. There are differences therefore. Only a careful analysis of the network equipment, the relationship between the structure and operation of the power grid, in order to grasp the relationship between energy consumption and its influencing factors of distribution network, and system A technical scheme of reducing power loss in line with energy saving goals, summed up the potential of energy saving and comprehensive analysis method to make energy-saving work more targeted. At the same time, the difference of distribution network energy saving is not only to meet the optimization problem of different energy saving technology of a single line, but also meet the distribution lines of energy economy and operation condition the multi-objective programming problem, only through the establishment of reasonable planning model, can from the perspective of the system of distribution network planning to achieve energy-saving significance. Firstly, according to the network equipment and operation of distribution of loss mechanism analysis, and summarizes the methods of energy saving technology of distribution network correspondence, on the basis of energy saving technology index the formation of technological transformation, energy-saving standards, complete the analysis to establish the system of energy distribution network. Secondly, according to the distribution network energy saving potential lack of comprehensive quantitative evaluation Study on the problem, according to the different power grid data acquisition, prediction method combined with power flow calculation and grey correlation, respectively, forming a typical circuit and the energy saving potential of distribution network based on evaluation method based on the analysis of the energy saving potential applied to the different characteristics of the distribution network. In view of the current distribution network mostly only a single line of different energy saving technology optimization, lack of system of distribution network reliability and economy of the planning problem, the index of energy saving and cost constraints to meet the requirements of Power Grid Corp under the condition that the establishment of two level programming model of distribution network partition analysis of energy saving technical differences based on the completion of the technical transformation scheme of energy saving and energy saving investment make optimal allocation. Finally according to the analysis the function demand, build distribution network energy aided analysis software platform, combined with an example, the software can realize the power distribution system The energy saving potential assessment and energy saving planning of the network have good engineering application value.
