Embodiment Construction

[0011] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, the solar-diesel hybrid system can be divided into four units. The power generation unit is composed of a wind generator 101, a solar cell assembly 102, a main diesel generator 103 and a backup diesel generator 104. The rectification unit is composed of a fan controller 105, a solar control The battery is composed of a device 106 and a charging controller 107, the energy storage unit is a storage battery 109, and the control unit is a centralized controller 110.

[0013] The wind power generator 101 converts wind energy into AC power, which is rectified by the wind turbine controller 105 and collected to the DC bus 108 to be sent to the battery 109 . The solar battery module 102 converts solar energy into direct current, which is rectified by the solar controller 106 and collected to the direct current bus 10...

Abstract

The invention provides a wind-solar-diesel hybrid system control method. The wind-solar-diesel hybrid system control method includes the following steps: collecting data, comparing and analyzing the data, and adjusting working modes according to comparison results. The collected data include storage battery data, diesel oil power generation data and time data. The working modes include a wind driven generator working mode, a solar battery array working mode, a diesel generator working mode, a storage battery working mode and a load working mode. By means of the wind-solar-diesel hybrid system control method, intelligent control over a wind-solar-diesel hybrid system is achieved, unified management and coordination on wind power generation, solar power generation and diesel generator power generation are achieved, and stability and reliability of operation of the wind-solar-diesel hybrid system are integrally improved.

Description

technical field [0001] The invention relates to a control technology of a power generation and power supply system, in particular to a control technology of a wind-solar-firewood complementary system applied to a communication base station. Background technique [0002] With the progress and development of society, people's demand for communication continues to increase. There are many difficulties in the construction of the communication network, one of which is that it is impossible to lay the mains electricity or the laying cost is expensive, such as islands or remote areas. The complementary system of wind and firewood solves this problem well. [0003] The control technology of the current solar-diesel hybrid system is relatively simple. The power generation units of wind power generation, solar power generation and diesel generators work independently. Unified management and control greatly reduces the stability and reliability of system operation. Contents of the ...
