增供电量作为新建输变电工程生产运行后评价的一个重要指标,计算结果对电网新增负荷的效用评价有很大影响,是协调电网项目建设和地区负荷发展的有力工具。现存的计算方法有的不科学,有的划分范围不恰当。从工程实践方面重新对增供电量进行定义,在此基础上形成一种新的增供电量影响范围划分思路,对于公共网络输变电工程进行分类,总结专家的经验,提出了兼顾变电站性质和站间电网联接关系的输变电工程增供电量区域划分原则,使得增供电量计算工作流程标准化、规范化。按此原则给出了每种典型的输变电工程的增供电量的计算方法,具有较强的工程实用性。
As an important indicator of post-production evaluation of transmission and transformation project, the calculation result has great influence on utility evaluation of new load of power grid and is a powerful tool to coordinate the construction of grid project and regional load development. Some of the existing calculation methods are unscientific, and some are not properly classified. From the engineering practice to re-define the additional power supply, based on this form a new idea of dividing the range of power supply capacity, classification of public network transmission and distribution project, summarize the experience of experts, put forward to take into account the nature of the substation and The principle of regional division of power transmission and transformation project for power transmission network connection between stations makes standardization and standardization of work flow of power supply calculation. According to this principle, the calculation method of power supply for each typical power transmission and transformation project is given, which has strong engineering practicability.
