Problems solved by technology

[0003] The existing theoretical line loss calculation often uses a single calculation method to calculate the line loss of different types of voltage levels. Since the power grids of different voltage levels have different characteristics, a single method is used to calculate the theoretical line loss of different types of power grids. Inaccurate result

Abstract

The invention relates to a method and a system for calculating theoretical line loss of a power grid. The method comprises steps: device parameters, operation parameters and topological data are acquired; a to-be-measured object is acquired, and a corresponding calculation method is determined according to the type of the to-be-measured object; and a corresponding calculation method is called, data needed by the corresponding calculation method are acquired from the device parameters, the operation parameters and the topological data, and theoretical line loss of the to-be-measured object is calculated and outputted. According to the power grid theoretical line loss calculation method of the invention, a corresponding calculation method is matched for a different to-be-measured object, data needed for calculation are automatically acquired from an existing power grid service management platform, the theoretical line loss of the power grid can be calculated in real time, and as a different to-be-measured object adopts a different calculation method, features of each to-be-measured object and features of each calculation method are fully considered, and each to-be-measured object is matched with a corresponding calculation method so as to improve the theoretical line loss calculation accuracy.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method and system for calculating theoretical line losses of power grids. Background technique [0002] Theoretical line loss is the theoretically calculated line loss based on the parameters of the power supply equipment, the current operation mode of the power network, the power flow distribution and the load situation. Theoretical calculation of line loss is an important technical management means to reduce loss and save energy, and strengthen line loss management. Through theoretical calculation, we can find the distribution law of electric energy loss in the power grid. Through calculation and analysis, we can expose management and technical problems, and provide theoretical and technical basis for loss reduction work. Theoretical calculation of line loss. [0003] The existing theoretical line loss calculations often use a single calculation method to calculate the ...
