A Calculation Method of Network Loss Change Caused by Power Transmission and Transformation Equipment Maintenance

Abstract

The invention provides a calculation method of network loss change caused by transmission and transformation equipment overhaul, and belongs to the technical field of power overhaul. The method has two calculation modes: calculation before overhaul and calculation after overhaul. The method comprises the following steps: acquiring overhaul information and historical sections according to the two calculation modes; setting an integration period according to overhaul time; for the historical sections at different moments, calculating the power grid loss of each historical section in integrationperiods before and after a reverse operation; summing up to obtain the total grid power loss before and after the reverse operation; and obtaining the total power loss of the grid under the conditionof equipment commissioning and outage according to the initial state of the equipment to finally obtain the grid loss changes before and after equipment commissioning and outage. Through adoption of the method, the change of power network loss caused by equipment overhaul can be analyzed during formulation of an overhaul plan so as to rationally arrange the overhaul plan.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance, and in particular relates to a calculation method for power grid network loss changes caused by power transmission and transformation equipment maintenance. Background technique [0002] Electric energy is a secondary energy obtained from primary energy conversion, which can be converted into mechanical energy, thermal energy, magnetic energy, etc. With the development of society, electric energy has become the lifeblood of national economic development, and its application has penetrated into various fields of production and life. [0003] The power transmission and transformation equipment is inseparable from the power grid in the process of transmitting and distributing electric energy, so it is particularly important to ensure the normal operation of the power transmission and transformation equipment. Power transmission and transformation equipment in normal operation may...
