Problems solved by technology

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project was put into operation, its line loss rate has always been calculated manually, which is inefficient and outdated in management methods, which increases the difficulty of line loss analysis.
As a new voltage level, the influencing factors of 750 kV line loss are relatively complex, and there is no complete plan to follow for its theoretical calculation, real-time monitoring and analysis. Therefore, a real-time monitoring, calculation and analysis system for 750 kV power grid line loss is studied , it is very necessary for the management of 750 kV power grid and the improvement of economic operation level

Embodiment Construction

[0019] Such as figure 1 As shown, the existing power automation system is composed of EMS system 100, TMR system 200, and weather management system 300, which respectively provide external data access interfaces. These three systems are independent of each other and have not been integrated. The EMS system 100 provides the power data of each line and transformer power equipment every 30 minutes, including current, voltage, active power, reactive power, etc., and generates a daily data file (.dat) package and publishes it to the FTP server 400; the TMR system 200 provides The meter reading data of each line and transformer at intervals of 30 minutes, including the on-grid power and off-grid power of the line, the high, medium and low voltage forward power of the transformer and the high, medium and low voltage reverse power, etc., and generate daily The data file package (.dat) is published to the FTP server 400; the meteorological management system 300 provides a WebService da...

Abstract

The invention relates to a grid line loss monitoring and analyzing system, which utilizes data in an electric power automation system to perform real-time monitoring and analysis on grid line loss. The system comprises a data acquisition server, a database and an application server, wherein the data of the electric power automation system is connected with the data acquisition server through an FTP server and a data access interface; the data acquisition server comprises a data acquisition module and a line loss computation module; the database comprises an EMS data sheet module, a TMR data sheet module, a meteorological data sheet module and a line loss sheet module; and the application server comprises a basic data management module, an actual line loss analysis module, a theoretical line loss analysis module, a line loss comparative analysis module, a line loss statistical report module, a system configuration module, a user management module and a wiring diagram navigation module. By utilizing the conventional electric power automation system effectively, the line loss management level and working efficiency are improved, and a scientific basis is provided for the formulation and implementation of loss reduction measures.

Description

technical field [0001] The invention relates to a line loss monitoring and analysis system for a power grid, in particular to a line loss monitoring and analysis system for 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 line loss are relatively compl...
