Embodiment Construction

[0018] The present invention will be further elaborated below in conjunction with accompanying drawing:

[0019] Such as figure 1 As shown, the wind-solar hybrid power system in the present invention mainly includes solar panels, wind generators, rectifier unloaders, battery packs, switching power supply modules, central processing unit modules, GPRS monitoring and communication modules, and several general power supply modules. Universal power supply module, ring CAN bus, ring 485 bus.

[0020] The GPRS monitoring communication module is composed of a highly anti-interference microprocessor and a GPRS communication module. Its functions mainly include the following three aspects: 1. Monitoring the communication, control, and power supply links of the system, performing fault diagnosis, and counting the number of faults and faults. Type and fault distribution, automatically generate a self-test report and store it in the external memory; 2. When the central processing unit cr...

Abstract

The invention provides a high-reliability wind and light complementary communication power supply system in a full redundancy form in order to overcome the defects of high fault rate and poor maintaining convenience for the existing wind and light complementary system. Aiming at the power supply part, a novel rectification load discharger is designed; the reliability of the power supply part is improved by adopting a wind and light general power supply module; the communication reliability is ensured by adopting a CAN (controller area network) and a 485 two-stage ring bus; the reliability of the control part is ensured by adopting a mutual monitoring and controlling mode of a central processing unit and a GPRS (general packet radio service) monitoring and controlling communication module, thus all the power supply part, the communication part and the control part in the system have redundancy characteristics. The system not only can detect the fault in real time, but also can process effectively according to the existent fault; each individual part in the power supply system of electric equipment can not influence the operation of the whole system because of invalid fault, the system recombines and controls again according to the grade of the fault, or the origional performances are kept maximally at the cost of the corresponding performance loss, and when the fault reaches certain limit, external alarming is carried out to inform proffesional staff of overhaul.

Description

technical field [0001] The invention relates to a power supply system, in particular to a fully redundant wind-solar complementary power supply system with high reliability. Background technique [0002] At present, with the rapid increase in the construction and transformation of communication operators' base stations, power consumption accounts for a large proportion of energy consumption in the communication industry. In response to the national call for energy conservation, emission reduction, and low-carbon environmental protection, energy-saving solutions that make full use of new energy sources are gradually receiving more and more attention. Among them, renewable energy power generation equipment represented by solar energy and wind energy to drive base station operation is the best application mode today. In recent years, various operators have developed independent solar or wind-solar complementary power supply base stations in remote areas without power facilitie...
