Transmission network security test system of power system

Abstract

The invention belongs to the technical field of electric network security test, and discloses a transmission network security test system of a power system. The system comprises a test command input module, an initial parameter configuration module, a central control module, a wireless communication module, an expert suggestion module, an alarm module, a display module and a power load predictionmodule. The expert suggestion module provided by the invention can provide more professional guidance suggestions to staff, to ensure professionalism of power network security tests, and reduce accident occurrence probability caused by human. The system analyzes characteristics of periodic changing trend of electric power load through the power load prediction module, and a sinusoidal function model is used as a basic model of prediction data, and has advantages of conforming to actual changes of electric load data. In order to overcome a shortcoming that error is relatively high using the sinusoidal function as the basic model, the system also uses the method of repeative learning to improve accuracy of the prediction.

Description

technical field [0001] The invention belongs to the technical field of electric network safety testing, and in particular relates to a power system transmission network safety testing system. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The power system is an electric energy production and consumption system composed of power plants, power transmission and transformation lines, power supply and distribution stations, and power consumption. Its function is to convert the primary energy in nature into electric energy through the power generation device, and then supply the electric energy to various users through power transmission, transformation and distribution. In order to realize this function, the power system also has corresponding information and control systems in various links and different levels to measure, adjust, control, protect, communicate and dispatch the production process of ele...

Problems solved by technology

[0010] During the existing power grid safety test, due to the different professional levels of the test staff, the test is prone to unprofessionalism, resulting in operational accidents; at the same time, the existing power load prediction error is large, which is not conducive to the accuracy of the power grid safety test

[0011] The existing technology cannot accurately predict the security of the power system transmission network, cannot optimize the security prediction of the transmission network, improve production efficiency, and cannot adapt to various changes caused by seasonal changes in enterprises
