Abstract

The invention discloses a power supply system for power system monitoring equipment. The power supply system comprises an inductive power taking module, a solar power supply module, a battery and a power management module, wherein the power management module controls a first switch to switch off when energy of the inductive power taking module or the solar power supply module is greater than energy required by a load; and the power management module controls a first switch to switch on when energy of the inductive power taking module and the solar power supply module is less than energy required by the load, so that the battery supplies power to the load. The power supply system provided by the invention adopts the power supply method of combining inductive power taking, solar power supplyand battery, preferentially uses the power of the inductive power taking module and the solar power supply module and then uses the power of the battery, thus ensures the power supply continuity, reduces the number of battery replacements, and brings convenience to the staff; in addition, due to the participation of solar power supply, the cost of power supply is reduced.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a power supply system for power system monitoring equipment. Background technique [0002] Smart grid has become a new trend in the development of the world's power grids. Faced with new challenges and new situations, the State Grid Corporation of my country proposed to accelerate the construction of UHV as the backbone grid, coordinate the development of power grids at all levels, and integrate information technology, automation, The strategic goal of a strong smart grid characterized by interaction. According to the demand of smart grid, intelligent monitoring equipment will be widely promoted and applied. In the application scenarios such as outdoor suburbs without wired power supply, how to provide safe and stable power supply for monitoring equipment is the first problem that intelligent monitoring equipment must face when it is widely used. question. A common power su...
