The DNO assesses the network is capable of withstanding an export of 240A (4.6MW at nominal voltage and unity power factor) for the state 2 design time of five minutes. The relay is set to 400A; the maximum unrestricted export from the site would be 250A. The protection does not present any limitations. Voltage Assessment:
Connection Point. The Agreed Export Capacity shall be no lower than 3.68kW per phase. Distribution System through the Connection Point. The product of voltage and current at fundamental frequency, and the square root of three in the case of three-phase systems, usually expressed in kilovolt-amperes ('kVA') or megavolt-amperes ('MVA').
Step up the current to give an export Active Power equivalent to 105% of the export Active Power limit (for Test A), Check that change in export level is “seen” by the PMU. Check that the Active Power exported by the generation reduces to a value at least 5% below the export limit setting within the specified reaction time.
To limit export of power across the point of interconnection, a reverse power protective function is implemented using a utility grade protective relay. The default setting for this protective function shall be 0.1% (export) of the service transformer’s nominal base Nameplate Rating, with a maximum 2.0 second time delay to limit Inadvertent Export.
It will only allow a site to export what the Distribution Network Operators (DNOs) permit. G100 generally refers to the energy export limiting of the combination of inverters and power management equipment such as a smart meter - very rarely does an inverter (or series of inverters) get approved to export limit on its own.
