Abstract

The invention discloses an optical selection method, based on total life cycle costs, of transformer station reactive power compensation devices. The method comprises the following several steps: (1) establishing total life cycle cost models of different types of reactive compensation devices, (2) determining values of calculation parameters of various costs of the total life cycle cost models, (3) performing basic calculation and comparison of total life cycle costs on the different types of reactive compensation devices according to the calculation parameters to obtain different advantages of the different types of reactive compensation devices in total life cycle cost, (4) performing sensitivity analyses on the different types of reactive compensation devices, (5) performing benefit evaluation on the different types of reactive compensation devices, and calculating results according to the total life cycle costs to obtain a comparison of cost effectiveness on the condition that a reactive compensation equivalent benefit is considered. The invention provides the optical selection method of the transformer station reactive power compensation device, improves voltage quality to the maximum extent, reduces losses to the maximum extent, and guarantees safe, stable and economic running of a power grid.

Description

technical field [0001] The invention relates to a method for optimizing reactive power compensation devices of substations based on full life cycle costs, and belongs to the technical field of configuration of reactive power compensation devices. Background technique [0002] Due to the needs of reactive power flow, guaranteed voltage level, and reduced loss, shunt compensation capacitors and reactors are widely used in power grids and user sides of various voltage levels. With the development of large-capacity long-distance power transmission and the improvement of power quality requirements, dynamic reactive power compensation devices have received widespread attention and gradually gained their due in the power grid. [0003] At present, the comparison of reactive power compensation devices is mainly concentrated on the technical level, and the investment cost is mainly considered in terms of cost. The reactive power compensation device, especially the dynamic reactive p...
