LOW VOLTAGE RIDE THROUGH DETECTION SYSTEM SUITED FOR USE IN LARGE-SCALE PHOTOVOLTAIC POWER STATIONS IN HIGH-ALTITUDE REGIONS

摘要

The present invention discloses a low voltage ride through detection system for use in large-scale photovoltaic power stations in high-altitude regions, characterised in that the detection system uses a vehicle-mounted container structure and that the integrated design is concentrated within 3 containers, said 3 containers being a 10kV voltage dip divider, a 35kV voltage dip divider, and a switch cabinet container. The present system carries out strict electrical detection on key networked devices in grid-connected photovoltaic power stations. Use of the present system is greatly significant for promoting the sustainable and healthy development of the photovoltaic industry, avoiding the occurrence of network loss incidents in large-scale photovoltaic power stations and solving technical problems relating to the safe and steady operation of grid-connected large-scale photovoltaic power generation.
