220kV Photovoltaic Grid-Connected Relay Protection Configuration

220kV Photovoltaic Grid-Connected Relay Protection Configuration

The 110 and 220 kV lines of the main grid are protected by means of two primary protection schemes (two distance relays or a distance and a differential line relay) or a primary protection relay (distance relay) and a backup protection relay (overcurrent. Moreover, the advantages of photovoltaic panels are numerous, both in terms of duration of the installation and in terms of reduced maintenance costs, this ensures that the tr nd and the investments are destined to continue. Modern solar photovoltaic (PV) power plants typically generate electricity at low voltages, ranging from 400V to 800V. To efficiently export this electricity to the utility grid, the generated voltage must be stepped up to medium or high voltage levels—such as 11kV, 33kV, 66kV, or 132kV—depending. In this paper, EasyPower computer program is used with the module Power Protector. The function and the ANSI codes for different relays have been discussed for a Line-.
