Embodiment

[0049] The energy management mechanism provided by the invention can be applied to solar power supply equipment in the power transmission line status monitoring system. For example, in a 12V DC solar power supply system, including solar panels, batteries, solar charge and discharge controllers and several loads, such as figure 1 shown. The solar charge and discharge controller can be switched between normal state, abnormal state and dormant state, which can make such as figure 2 V1=11V shown, V2=10V, V3=10.5V, V4=11.5V. In this way, when the solar charge and discharge controller is working in a normal state, the solar charge and discharge controller will enter an abnormal state when the voltage is lower than 11V when the power is insufficient and the voltage drops due to insufficient sunlight. Because various loads with a rated power supply voltage of 12V may not work normally when the voltage is lower than 11V, it is unnecessary to continue to consume power in such a situa...

Abstract

The invention belongs to the technical field of power system communication and relates to an energy management system and method for monitoring solar energy power supply equipment in a power transmission line state. The energy management system comprises a solar energy charging and discharging controller as well as a load, a solar energy panel and a storage battery which are respectively connected with the solar energy charging and discharging controller; the solar energy charging and discharging controller comprises a state control circuit and a Beidou system module which are sequentially connected, and the solar energy charging and discharging controller switches among three states, namely a normal state, a non-normal state and a dormant state by virtue of a state control circuit in the solar energy charging and discharging controller; and the Beidou system module accepts uniform time service and control of a Beidou system, so that loads are cut off at the same time to save electric power, and the loads are accessed to acquire and transmit data. By adopting the energy management system and method for monitoring the solar energy power supply equipment in the power transmission line state, the whole power transmission line state monitoring system periodically operates, and the aim of reducing average power consumption is achieved.

Description

technical field [0001] The invention belongs to the technical field of power system communication, and relates to an energy management system and method for monitoring the state of a transmission line for solar power supply equipment, and in particular to an energy management system and method for monitoring the state of a transmission line for solar power supply equipment. Background technique [0002] The transmission line status monitoring system includes the main station of the system, the communication network and the monitoring terminal. The monitoring terminal can monitor various useful status information of the transmission line and transmit them to the main station of the system through the communication network. Monitoring terminals and communication equipment are located on transmission line towers, which are generally powered by solar power. Because the power supply capacity of the solar power supply method is limited, the average power consumption of the monitor...
