Description
Technical Field
The utility model relates to a photovoltaic power generation technology especially relates to photovoltaic power generation system.
Background
The photovoltaic power generation is green and environment-friendly, energy-saving and emission-reducing, and is the direction of future energy development, however, the output electric energy of a single photovoltaic cell component is small in the using process, and the increasing energy demand cannot be met, so that a plurality of photovoltaic cell components need to form a system, the photovoltaic power generation is integrated, and a photovoltaic power generation system is developed. In particular, a photovoltaic power generation system refers to a power generation system that directly converts light energy into electric energy without a thermal process. Its main components are solar cell, accumulator, controller and inverter. The device has the characteristics of high reliability, long service life, no environmental pollution, independent power generation and grid-connected operation. The photovoltaic power generation system has the following functions:
(1) a photovoltaic Array (PV Array) is a dc power generation unit formed by assembling a plurality of photovoltaic modules or photovoltaic panels together in a certain manner and having a stable support structure, and in the case of illumination (whether sunlight or illumination generated by other illuminants), a battery absorbs light energy, and accumulation of charges of different signs occurs at two ends of the battery, i.e. a "photovoltaic voltage" is generated. This is the "photovoltaic effect". Under the action of photovoltaic effect, the two ends of the solar cell generate electromotive force to convert light energy into electric energy to complete energy conversion
(2) The storage battery pack (optional) has the functions of storing electric energy generated by a solar cell matrix when being illuminated and supplying power to a load at any time, and the basic requirements of the storage battery pack for solar cell power generation are that ① self-discharge rate is low, ② service life is long, ③ deep discharge capacity is strong, ④ charging efficiency is high, ⑤ is low in maintenance or free of maintenance, ⑥ working temperature range is wide, and ⑦ price is low.
(3) Battery controller (optional). A battery controller is a device that can automatically prevent overcharge and overdischarge of a battery. Since the number of cycles and the depth of discharge of the secondary battery are important factors for determining the service life of the secondary battery, a battery controller capable of controlling overcharge or overdischarge of the secondary battery is indispensable
(4) An inverter. An inverter is a device that converts direct current to alternating current. When the solar cell and the storage battery are direct current power sources and the load is an alternating current load, an inverter is indispensable; the inverters can be divided into an off-grid inverter and a grid-connected inverter according to operation modes. The off-grid inverter is used for an independently operating solar cell power generation system to supply power to a load. The grid-connected inverter is used for a solar cell power generation system which operates in a grid-connected mode. The inverter can be divided into a square wave inverter and a sine wave inverter according to the output waveform, has simple circuits and low manufacturing cost, but has large harmonic component, and is generally used for systems with the power of hundreds of watts or less and low requirements on harmonic. The sine wave inverter is high in cost, but can be applied to various loads.
(5) A tracking system. Compared with a solar photovoltaic power generation system in a certain fixed place, the solar photovoltaic power generation system has the advantages that the solar illumination angle changes all the time and at all times every day when the solar photovoltaic power generation system rises and falls all the year round every day, and the power generation efficiency can reach the optimal state only if the solar cell panel can face the sun all the time. In general, a sun tracking control system in the world needs to calculate the angle of the sun at different times of each day in a year according to information such as longitude and latitude of a placement point, and store the position of the sun at each time in the year into a PLC (programmable logic controller), a singlechip or computer software, namely, a computer data theory is adopted for realizing tracking by calculating the position of the sun. Data and setting of latitude and longitude regions of the earth are needed, once the device is installed, the device is inconvenient to move or assemble and disassemble, and the data must be reset and various parameters must be adjusted after the device is moved every time.
However, due to the characteristics of small scale, dispersion, large system quantity and centralized data transmission of the existing household photovoltaic users, the time consumption of the photovoltaic power generation system in data acquisition and data transmission is long, the transmission time is prolonged, and the household photovoltaic power generation system is not easy to acquire and monitor the data of the photovoltaic power generation system in time.
