The invention provides a comprehensive experimental platform for a power quality and energy-saving equipment based on the thinking of an artificial intelligence robot. The comprehensive experimental platform adopts a high-power electronic interface device to replace the conventional power amplifier so as to improve the electrical parameters of the interface and at the same time, realize greater power handling capacity to solve the problem of performance restrictions of power amplifiers in digital-physical hybrid simulation. The platform is regarded as an intelligent robot, and the structure and the function of the platform are divided based on a perception unit, a planning unit and an implementation unit of the robot. The platform robot can plan the operation of the next step according to the perceived system information and then realize the planning through the implementation unit. The comprehensive experimental platform makes use of the repeatability in the experimental process and the self-learning ability of the platform robot, and adopts a successive approximation method of repeated experiments to enable the experimental process to eventually reach the required operating conditions. Finally, based on the parameters tallied with the experimental requirements, the comprehensive experimental platform analyzes the performances of the power quality equipment and completes the experimental process.
Description
technical field [0001] The invention relates to a comprehensive experiment platform for power quality and energy-saving equipment, belonging to the field of power quality control and equipment improvement experiment methods and experiment platforms. Background technique [0002] Power quality is a system problem, not only related to the load, but also related to the network structure, system parameters and operation mode of the system. Therefore, the assessment of power quality equipment not only needs to test various electrical parameters and performance of the equipment, but more importantly, Put the equipment in the power system, and comprehensively measure the operation function and various performance indicators of the equipment. Therefore, it is necessary to establish the assessment of power quality equipment on a real-time simulation platform based on the power system, and provide experimental capabilities with high voltage and high current. [0003] With the widespr...
