Title:
POWER GRID AND GRID LOAD SIMULATION TESTING SYSTEM APPARATUS, AND ANTI-ISLANDING TESTING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/114537
Kind Code:
A1
Abstract:
A power grid and grid load simulation testing system apparatus, and an anti-islanding testing method thereof. A power grid and a grid load are simulated. The apparatus comprises an ammeter, a voltmeter, an alternating current voltage source, and an electronic load module. The alternating current voltage source is controlled, and the controlled mode is that a power grid setting value Uset is outputted in an alternating current source state, or the controlled mode is that a voltage value calculated by a load model is outputted in an electronic load state. The built load simulation RLC circuit mathematical model is in an ideal state, thus the calculation and simulation results are more accurate, and the volume of the testing system is reduced. Mechanical load adjustment is not required any more, and therefore, the operation is simple, and the experiment efficiency is improved.
