Dynamic increasing capacity on-line monitoring device for power transmission line

Abstract

The invention relates to a dynamic increasing capacity on-line monitoring device for a power transmission line, which is characterized by comprising a monitoring substation, a monitoring master station and a monitoring upper computer, wherein the monitoring substation is arranged on the power transmission line; the monitoring master station is arranged on a tower; the monitoring upper computer is arranged at a monitoring center; the monitoring substation comprises a STM32 singlechip, an intelligent protection CT (Current Transformer) power supply, a wire temperature sensor, an RF radio frequency module and a current transformer; and the monitoring master station comprises a STM32 singlechip master station control system, a photovoltaic power supply, a GPRS (General Packet Radio Service) module, a RF radio frequency module, an environment temperature and humidity sensor, a wind speed and direction sensor and a solar radiation sensor. The conveying potential of the line is sufficiently explored, the conveying capacity is timely according to the actual operation sate of a wire, the safety operation of the power transmission line is ensured, the risk caused by the increasing capacity is avoided, and the dynamic increasing capacity on-line monitoring device has an active effect of meeting the requirement on rapid growth of the social economy.

Description

technical field [0001] The invention relates to a high-voltage transmission power monitoring device, in particular to an on-line monitoring device for dynamically increasing the capacity of a transmission line. Background technique [0002] In recent years, the rapid growth of my country's national economy has led to a sharp increase in electricity load. In many economically developed provinces and regions, especially in East China, due to the growth of electricity load exceeding the development speed of electric power construction, there has been a serious shortage of transmission capacity of overhead transmission lines, and the economic benefits and corporate image of power companies have been damaged. In order to solve the increasingly serious power supply problem and improve the power supply capacity and economic benefits of the power grid, it is urgent to increase the transmission capacity of the transmission line. In the early days, the capacity increase of transmissi...

Problems solved by technology

The disadvantage is that the power-taking module has no discharge protection, and once the high-voltage line is overloaded, the power-taking module is easily burned

And the lithium battery used must not be overcharged, overcharged, resistant to high temperature, severe cold, and has a short service life
