Isolated network solar-wind-oil hybrid electricity generating system

Abstract

The invention discloses an isolated network solar-wind-oil hybrid power generating system which comprises a photoelectric unit, a wind electricity unit, an oil electricity unit, an energy storage unit, an alternating current sensor, a surplus power charging unit, a direct-current storage controller, an alternating-current electricity utilization controller, an inverter, a man-machine operating fault warning unit, a metering unit, an electricity utilization unit, a power switch and a voltage stabilizing module. An isolated network system of an independent system is formed through combination of intelligent monitoring and a software optimization algorithm, and a grid-connected interface connected with other power grids is reserved. According to the isolated network solar-wind-oil hybrid power generating system, firstly, peak load regulation is carried out by the adoption of an energy storage station (energy storage unit), the isolated network solar-wind-oil hybrid power generating system replaces the function of the state grid during isolated network running, and electricity utilization and storage are automatically regulated; secondly, natural and clean energy obtained through photovoltaic collection, wind energy collection and the like is adopted for supplement of electricity utilization, and can replace a part of diesel consumption, and finally the aims of reducing diesel consumption, saving energy and reducing emission are achieved.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to an isolated network light, wind and oil hybrid power generation system. [0002] Background technique [0003] In remote mountainous areas, especially in the mountains, mining resources are required to use electricity. The cost of setting up power transmission lines in these mountainous areas is very high for the State Grid, and it is impossible to demonstrate in a short time whether it is necessary to erect power transmission lines. At this time, usually They all use diesel generators to generate electricity on site to solve work and domestic electricity consumption. However, the use and maintenance costs of diesel generators are relatively high, and they also pollute the surrounding environment to a certain extent. [0004] With the gradual exhaustion of non-renewable energy development and rising oil prices, the use and maintenance costs of diesel genera...

Problems solved by technology

[0005] However, in the current environment-friendly power consumption mode, although independent photovoltaic power generation or wind power generation can also solve certain power consumption problems, there are cloudy days, rainy days and nights for photovoltaic power generation after all; Wind, or insufficient wind power, all these make it difficult to guarantee electricity consumption for work and life 24 hours a day
