Power management system and method for online monitoring device of power distribution line

Abstract

The invention discloses a power management system and method for an online monitoring device of a power distribution line. The system comprises an off-grid power supply module, a power management module and an online monitoring host. The off-grid power supply module includes a storage battery providing work voltage for devices of the online monitoring host and includes a power generating device for charging the storage battery, which charges a standby battery in the power management module at the same time. The system communicates with a monitoring center through wireless communication, adopts remote monitoring or system automatic control techniques, conducts real-time or timed monitoring and control of the battery life and the temperature of the storage battery, and controls the connection and disconnection between the storage battery and the online monitoring host. The system is of great importance to normal operation of an online monitoring device of a high-voltage power distribution line.

Description

technical field [0001] The invention belongs to the field of long-distance power transmission, and in particular relates to a power management system and method for an online monitoring device of a transmission line, which ensures continuous and effective operation of the monitoring device for a high-voltage transmission line.

Problems solved by technology

[0002] With the continuous improvement of energy consumption, the voltage level of electricity is getting higher and higher, and the line inspection, maintenance, operation and management become more and more difficult. The stability, safety and ability to prevent natural disasters of my country's power grid will also face challenges At the same time, the inspection, maintenance and management of long-distance transmission lines will encounter new difficulties and challenges. Electricity is an important basic energy source, and its normal, stable and safe operation will be related to national development and In all aspects of residents' lives, the environment in which high-voltage transmission lines operate is generally very remote areas, the natural environment is complex and changeable, and severe weather conditions may cause transmission line failures, and some areas cannot cover mobile networks

[0003] Now the automation level of the power grid is gradually improving. With its remarkable advantages, wireless communication has become an important means of communication in the online monitoring system of high-voltage transmission lines. The problem of power supply is an important consideration for the on-line monitoring and monitoring equipment of high-voltage transmission lines. It is the basis for the normal operation of high-voltage transmission line monitoring equipment. At present, the power supply of high-voltage transmission line monitoring equipment uses solar panels combined with rechargeable batteries to provide power for monitoring equipment. However, there is no means to monitor the state of battery power and other conditions.
