Abstract
Disclosed are a method and system for testing high-voltage ride-through of a photovoltaic inverter. The method for testing high-voltage ride-through of a photovoltaic inverter includes: connecting a board-to-board (BTB) circuit to a passive circuit in series, and connecting circuit breakers to the passive circuit to form an inverter test device; connecting one end of the inverter test device to an alternating current power supply, and connecting the other end of the inverter test device to a tested apparatus; and performing testing by adjusting a parameter of the passive circuit and a switching mode of the circuit breakers by means of the BTB circuit. According to the present disclosure, an influence of the device for testing high-voltage ride-through of a photovoltaic inverter on power supply voltage is eliminated, a requirement on supply of reactive power of the power supply is eliminated, applicability is better, and cost is lower.
