Embodiment 1

[0024] Such as figure 1 It is an existing hybrid new energy off-grid power generation system for traditional wind, light, and mains complementary street lights. The street lamp is a 50-watt LED lamp head, and the longest daily light-on time is 12 hours. The battery is two sets of 12-volt 100-amp-hour lead-acid batteries, with a float charge voltage of 26 volts and an equal charge voltage of 28 volts. 24)*12=25 ampere hours, since the battery efficiency is generally about 75%, and the battery cannot be fully discharged, so the cycle of a full charge and discharge of the battery is about 2.5 days.

Embodiment 2

[0026] Taking wind energy, solar energy, and traditional energy (mains electricity) as examples, such as figure 2 The hybrid new energy off-grid power generation system of the present invention. In the off-grid power generation system of hybrid new energy, the wind energy converts the alternating frequency, variable voltage and variable power output of the generator into direct current through an independent controller and connects it to the system bus; solar energy is connected to the system bus through an independent controller; traditional energy ( Mains electricity or diesel generator) is connected to the system bus through a charger, and the battery and load are connected to the bus respectively.

[0027] In the control method of the hybrid new energy off-grid power generation system, the priority setting is wind energy, solar energy, and mains power (the use level of new energy can also be set arbitrarily according to needs).

Abstract

The invention relates to an off-grid power generation system adopting hybrid novel energy and a control method thereof. The off-grid power generation system comprises novel energy, traditional energy, a storage battery and a load; and the voltage values of the control systems of various forms of energy are set according to required priority levels, and the voltage which is set according to the top priority level is the highest. According to the invention, the novel energy is controlled to be utilized first by setting the floating charging and uniform charging voltage values in the off-grid power generation system. The off-grid power generation system adopting hybrid novel energy and the control method thereof can make the novel energy supply power to the load first and prolong the service life of the storage battery.

Description

technical field [0001] The invention relates to an off-grid power generation system using hybrid new energy and a control method thereof. Background technique [0002] Mains electricity is what we call alternating current (AC). The components of alternating current include: voltage, current, and frequency. The frequency can be divided into two types: 50HZ (Hertz) and 60HZ (Hertz). The voltage distribution ranges from 100VA to 240VA. Generally 220V (volts). [0003] Traditional energy refers to energy that has been widely used by people and is relatively mature in technology under the current scientific and technological level, such as coal, oil, natural gas, water energy, wood, etc. Traditional energy is also called conventional energy. Coal, oil and natural gas in traditional energy are all evolved from ancient biological fossils, so they are collectively called fossil fuels. [0004] New energy sources refer to various forms of energy other than traditional energy. Mos...
