摘要/Abstract

摘要：

110 kV电网πT混合网架结构在实际运行中存在运维量大、灵活性及可扩展性差的问题，无法满足日益提高的供电可靠性需求。针对上述问题，提出了πT混合电网结构的优化方案，并对优化方案进行技术经济论证；研究现有πT混合结构向链式π接结构过渡的改造方案，并制定110 kV电网的组网原则，指导110 kV电网πT混合网架结构优化的实施及落地。

关键词: 网架结构, πT混合, 链式π接, 单母分段

Abstract:

There are some operational problems of the πT hybrid structure, such as large workload of operation and maintenance, poor flexibility and scalability, which can not meet the increasing demand for power supply reliability. In this paper, the optimization scheme of the πT hybrid structure connection structure was put forward, and the technical and economic demonstration of the optimization scheme was carried out. The concrete alteration scheme of πT mode to chain π connection mode was studied, and the networking principle of 110 kV power grid was established, which can direct the implementation and landing of the optimization of the 110 kV power grid with πT hybrid structure.

Key words: network structure, πt hybrid, chain type π connection, single-bus section
