Abstract

The invention relates to a method and a device for monitoring and analyzing the line loss of a power grid. The method comprises the following steps of: establishing a power grid model parameter library through a series of analysis methods; acquiring real-time data, gateway meter data and meteorological data such as temperature data, humidity data and the like, storing in a database, and calculating actual line loss and theoretical line loss; calculating the tidal current of the power grid by using a Newton Raphson algorithm, and calculating the power loss of the power grid so as to calculate the theoretical line loss of the power grid; analyzing and comparing the line loss, searching error reasons and making analysis suggestions; and obtaining a result and ensuring the real-time property of the data. By comparing and analyzing a theoretical calculated value and an actual test calculated value of the line loss, an association relationship between the line loss of the power grid and factors such as a grid structure, the tidal current of the power grid, meteorological factors and the like is searched, the error reasons of the line loss are analyzed, the statistical calculation and analysis of the line loss of the power grid are guided, and scientific evidences are provided for making and performing loss reducing measures.

Description

technical field [0001] The invention relates to a method and system for monitoring and analyzing line loss of a power grid, in particular to a method and device for monitoring and analyzing line loss of a 750 kV power grid. Background technique [0002] Transmission network line loss rate is a comprehensive technical index that comprehensively reflects the level of power grid planning and design, production operation and management. The calculation and management of power grid line loss is one of the very important links in the safe and economical operation of the power system, and a set of perfect management methods and rules and regulations have also been formed. Since the 750 kV power transmission and transformation demonstration project was put into operation, its line loss rate has always been calculated manually, which is inefficient and outdated in management methods, making line loss analysis more difficult. As a new voltage level, the influencing factors of 750 kV ...
