Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0046] Such as figure 1 As shown, an economic optimization method for equipment monthly maintenance plan based on network loss reduction index includes the following steps:

[0047] S1. Data generation of benchmark power grid operation mode under the economic optimization of monthly maintenance plan for power transmission and transformation equipment:

[0048] On the basis of the calculation data of the power system's monthly planned power grid operation mode, and according to the monthly maintenance plan information of power transmission and transformation equipment, the maintenance equipment that cannot be changed within the month and the equipment whose maintenance cycle is the maximum number of days per month are classified according to their maintenance start date and maintenance cycle. Firstly arrange the maintenance, through the switchi...

Abstract

The invention provides a method for economically optimizing a monthly overhaul schedule of equipment based on a transmission loss decline index. The method comprises the following steps: generating reference power grid operation mode data under economic optimization of the monthly overhaul schedule; generating power grid operating mode calculation data of various adjustable overhaul equipment under different overhaul starting dates in an overhaul starting time interval; calculating a monthly transmission loss decline index of various adjustable overhaul equipment; and performing economically optimized arrangement of the adjustable overhaul equipment in a month under a security and stability constraint condition. According to the invention, based on a load flow calculation and time-domain simulation technology of a power system, the total transmission loss of the power grid operation mode under the monthly overhaul schedule of the equipment is reduced through optimal arrangement of the monthly overhaul schedule of the equipment; and thus, decision support is provided for economically optimized arrangement of the monthly overhaul schedule of power generation, transmission and transformation equipment of the power system.

Description

technical field [0001] The invention relates to the technical field of electric power systems and automation thereof, in particular to an economical optimization method for equipment monthly maintenance plans based on a network loss reduction index. Background technique [0002] The optimization of monthly maintenance plan for power generation, transmission and transformation equipment is one of the main contents in the short-term operation plan of the power system. The rationality of the maintenance plan for power generation, transmission and transformation equipment directly affects the economy of power system operation. With the in-depth promotion of lean management of power system operation and the development of computer and communication technologies, the traditional method of arranging equipment maintenance plans based on experience has gradually changed to the direction of intelligent decision-making, in order to achieve energy saving, emission reduction, and loss red...
