Abstract

The invention relates to the technical field of solar power generation, in particular to a novel solar power generation control system. The system comprises a solar photovoltaic array, a current and voltage collection circuit, a DSP chip, a PWM driving circuit, a DC/DC converter, a DC/AC inverter, a DC/DC voltage stabilization circuit, a storage battery charging/discharging controller, a storage battery pack, a discharge current resistance detection circuit, a voltage detection circuit, a current detection circuit, an alternating-current load and a direct-current load. According to the system, solar energy is converted into electric energy through the solar photovoltaic array, and current and voltage parameters output by the solar photovoltaic array are collected by utilizing the current and voltage collection circuit; meanwhile, signal adjustment is realized by utilizing the DC/DC converter, the DC/AC inverter and the DC/DC voltage stabilization circuit, so that normal work of the system can be ensured; and moreover, the internal resistance value of the storage battery pack is detected by utilizing the discharge current resistance detection circuit, so that the situation that the exception of the storage battery pack cannot be discovered in time is avoided.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a novel control system for solar power generation. Background technique [0002] As we all know, photovoltaic power generation (solar power generation) system is based on the maximum power generation. Therefore, the design of photovoltaic tracking system should not only avoid under-tracking, but also avoid over-tracking. fundamental facts. At present, the maximum power point tracking of the photovoltaic system is not perfect enough, and there is a lack of more reliable operation control for the charging work. Contents of the invention [0003] In view of the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a novel control system for solar power generation. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A new control system for solar power ge...
