Block supply-based distribution network planning design method

Abstract

The invention belongs to the field of power systems, in particular to a block supply-based distribution network planning design method. The method comprises the following steps of: adopting a typical power supply mode for defining main components and key points of a power network structure, a power supply unit, power network equipment and other power supply systems, and dividing a planning area into related, influenced and independent power supply regions in different levels according to functions, geographic orientation, administrative division and other conditions; adopting a planning design sequence from bottom to top to formulate a distribution network planning design scheme for each power supply region from the starting point of social and economic development and power demands in each power supply region; and finally forming a distribution network planning design scheme of the planning area through combined optimization. The block supply-based distribution network planning design method can formulate distribution points of the power network structure, transformer substations or power distribution stations, also can formulate a development program of each power supply unit and main equipment types of the power network, and is a distribution network planning design method which integrates planning and design and expands the conventional distribution network planning boundary.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a method for planning and designing a power grid based on regional power supply. Background technique [0002] The current power grid planning and design follows the principle that the superior planning guides the subordinate planning and the subordinate planning supports the superior planning. Usually, the layout and capacity of substations are increased, and the power supply line circuit is increased to meet the power demand, and some optimization methods are adopted and voltage and power flow are considered. and other constraints, with the goal of economy, reliability or line loss, optimize the layout of multiple substations and branch roads to be selected, and finally form a planning and design scheme. In fact, it is a top-down design method, that is, from the upper-level power grid to the lower-level power grid, and from the higher-voltage power grid to the lower-vol...
