【摘要】：随着经济与社会的发展,我国的电网建设已进入特高压、大电网阶段,其中,骨干网架的建设关系到未来数十年甚至上百年的电网结构与规模的适应性、合理性,依旧局限在电网投资的经济性评价上,已不能适应未来社会发展的需要,因此以大系统的观念从长远眼光对大电网进行综合经济性评价是现实的需求。大电网规划建设关系到国民经济发展、社会生活保障、资源的优化配置等综合效益,本文基于我国电网实际情况,通过统计资料数据分析,详细阐述了电网属性、国民经济、社会发展、能源资源、环境保护等方面对电网的影响；为了能够对电网经济性影响因素进行综合分析,运用系统工程模型化技术建立影响因素的解释结构模型,随后构建层次分明的多级递阶结构,得出电网经济性影响因素的五个层次,分析了电网属性等五大类影响因素对电网经济性的影响路径,通过分析影响因素与评价指标之间的关系,得出大电网规划的经济性评价指标的总体研究方向,为提出合理有效的经济性评价指标奠定基础；通过影响因素分析,将反映大电网与宏观经济社会关系的指标列入经济性评价指标体系,形成的大电网规划的经济性评价指标体系包括综合成本、经济效益、可靠性效益、社会效益、环境效益等,研究了各评价指标的计算方法;将前述指标方法运用于大电网算例,通过计算规划方案的经济性指标,综合分析评价规划方案的经济性,最后对大电网规划方案经济性评价问题进行分析,验证了所提指标及方法的科学合理性。
[Abstract]:With the development of economy and society, China's power grid construction has entered the UHV power grid, which is related to the stage, the next few decades or even hundreds of years of the scale of power grid structure and adaptability, rationality of backbone network construction, still remain in the economic evaluation of power grid investment, has been unable to meet the future needs of the society the development, therefore to the concept of the system from the long-term perspective on the power grid comprehensive economic evaluation is the realistic demand.
The large power grid planning and construction related to the national economic development, social security, comprehensive benefits to optimize the allocation of resources and the actual situation of China's power grid based on statistical data, through data analysis, elaborated the grid attribute, national economy and social development, energy resources, environmental protection and other aspects of influence on power grid; in order to carry out comprehensive analysis of the factors affecting the economy of power network, using system engineering modeling technology to establish the influence factors of, then constructs the hierarchical structure hierarchy, the five levels of power grid economic factors, analyzes the factors of path grid attributes and other five categories of influence on the economy of the power system, through the analysis of the relationship between among the influencing factors and evaluation index, the general direction of the economic evaluation index of power grid planning, put forward reasonable and effective evaluation of economy Basis price index; through the analysis of the influencing factors, will reflect the power of social relations and macroeconomic indicators included in the economic evaluation index system, the formation of large power grid planning and economic evaluation index system including comprehensive cost, economic benefits, social benefits, environmental benefits of reliability, efficiency, and studies the calculation methods of each evaluation index the index; method is applied to large power grid examples, through the economic index calculation of planning economy, comprehensive analysis and evaluation of the planning scheme, at the end of the large power grid planning of economic evaluation problem is analyzed, and it proves the index system and method.
