【摘要】：随着经济的发展和产业的变革,社会对供配电效率和电能质量的要求越来越高,电力企业所承受的节能减排压力也越来越大。尽管国内供电企业对电网节能减排开展了大量研究工作,但普遍集中在节能减排的途径、措施、效益、风险以及分析指标体系上,对节能减排的实际情况一般采用事后评估的方法,对于电网企业节能减排关键指标缺少进行事先的识别与考核,节能减排空间有待量化。本文以鄞州电网为研究对象,首先建立了新建项目、改造项目和新技术对线损率影响的关系模型,用以定量评估各类措施对线损率造成的影响；其次,在对鄞州现状电网能耗分析的基础上,找出了影响鄞州电网能耗的薄弱环节,分析了现状电网节能减排的空间；接着以鄞州规划电网为基础,在宏观定性分析规划电网对现状电网能耗薄弱环节的解决情况下,运用电网定量评估综合模型预测出各电压层级的线损率,最终预测出规划年电网的综合线损率,换算成年度节约电量,实现对节能减排关键措施节能效果的定量评估,得出规划电网的节能减排空间；最后,对电网企业内部各环节节能减排措施进行全面研究及总结,在结合边界条件设定相应的节能目标值的基础上,比较分析并指出电网自身节能是电网企业节能减排的关键措施,同时对鄞州电网提出相关节能减排措施策略,从而指导各项管理工作,促进管理水平的提高。
[Abstract]:With the development of economy and the change of industry, the demand of power supply and distribution efficiency and power quality is higher and higher, and the pressure of energy saving and emission reduction is increasing. Although domestic power supply enterprises have carried out a lot of research work on energy saving and emission reduction of power grid, they generally focus on the ways, measures, benefits, risks and analysis index system of energy saving and emission reduction. To the actual situation of energy saving and emission reduction, the method of ex post evaluation is generally adopted, and the key indexes of energy saving and emission reduction of power grid enterprises are lack of prior identification and assessment, and the space of energy saving and emission reduction needs to be quantified. In this paper, Yinzhou Power Grid is taken as the research object. Firstly, the relationship model of new project, reconstruction project and new technology on line loss rate is established to quantitatively evaluate the effect of various measures on line loss rate. Secondly, On the basis of energy consumption analysis of Yinzhou current power grid, the weakness of Yinzhou power grid energy consumption is found, and the space of energy saving and emission reduction is analyzed. Under the condition of solving the weak link of energy consumption in the current power grid through macroscopic qualitative analysis and planning, the line loss rate of each voltage level is predicted by using the comprehensive model of power grid quantitative evaluation, and finally the comprehensive line loss rate of the planned annual power network is forecasted. Conversion of power saving adult degree to achieve quantitative evaluation of energy saving and emission reduction key measures to achieve the planning of energy saving and emission reduction space. Finally, the energy saving measures in various links of power grid enterprises are studied and summarized in an all-round way. On the basis of setting the corresponding energy saving target value according to the boundary conditions, this paper compares and points out that the energy saving of power grid itself is the key measure of energy saving and emission reduction of power grid enterprises. At the same time, it puts forward the relevant energy saving and emission reduction measures for Yinzhou Power Grid. In order to guide the management work, promote the improvement of management level.
