Embodiment 1
[0121] Such as figure 1 As shown, when the control information sent by the bus board is short-circuited by the solar panel, the data is first isolated by the communication isolation unit, and then received by the control chip. The control chip receives the data for analysis and verification, and then drives the circuit through the MOS tube By controlling the conduction of the MOS transistors U4, U5, and U2, the control of the short circuit is completed at this time. Then, the collected voltage and current data of the solar panel are sent to the bus board through the communication isolation unit, and a control-acquisition process is completed so far.

Description
technical field [0001] The invention belongs to the technical field of intelligent control, and provides an acquisition board circuit of an intelligent photovoltaic power plant simulator. Background technique [0002] With the increasingly sophisticated research on photovoltaic power generation systems, large-scale photovoltaic power plants are increasing. How to make large-scale photovoltaic power plants unusable for experimental research is an urgent problem to be solved. Although the current power system and photovoltaic power generation technology are relatively common, how to convert photovoltaic power generation and mains power, and how to realize the simulation system of photovoltaic power generation and mains power conversion. Existing society lacks such technology. Contents of the invention [0003] The purpose of the present invention is to provide a collection board circuit of an intelligent photovoltaic power station simulator aiming at the deficiencies of th...
