Dual power supply system

Abstract

The invention relates to the field of new energy, in particular to a dual power supply system. With the rapid development of urbanization, the load of municipal power is increasing, and the energy consumption of urban electricity, especially road lighting, will be greatly increased. Public lighting is a large power consumer, and its annual electricity consumption accounts for 15% of the total power generation in the country. %about. In 2016, coal-fired power consumption in my country's annual lighting electricity consumption reached about 650 billion kWh, and coal-fired power generation consumed about 250 million tons of coal. At present, more than 99% of the public lighting on the market are illuminated by city circuit lights. Air pollution and smog weather are caused by excessive use of coal-fired power generation. To reduce air pollution and reduce coal-fired power generation The power consumption is a key measure. How to transform the existing traditional mains power supply system into a new system with dual power supply of mains power and new energy on the basis of its original basis, which will become the current traditional mains power supply system. Technical problems that need to be solved urgently encountered in the field of power supply.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a dual power supply system. Background technique [0002] With the rapid development of urbanization, the load of municipal power will continue to increase, and the load of road traffic facilities, such as charging piles for new energy vehicles, public lighting, etc., especially for urban lighting, will greatly increase the energy consumption of road lighting. , Public lighting such as highways and road lighting is a large power consumer, accounting for about 15% of the country's total power generation. In 2016, my country's annual power generation was 5,911.1 billion kwh, and the power consumption of public lighting reached about 880 billion kwh, of which thermal power generation accounted for 74.3%, and coal-fired power consumption reached about 650 billion kwh. Coal consumption reached about 250 million tons. Although the use of new energy lamps such as solar street lights can repla...

Problems solved by technology

Although the use of new energy lamps such as solar street lights can replace part of the traditional city circuit lighting, the defects of solar panels of solar street lights, such as low power generation efficiency and ineffective lighting in rainy days, limit the use of solar street lights in the lighting market to a certain extent. In addition, more than 99% of the public lighting on the market is illuminated by city circuit lights. It is unrealistic and impossible to overthrow all these traditional city circuit lights and replace them with new energy street lights such as solar street lights.
