IEEE Denver Section PES.IAS Chapter May 2019 Meeting

May 16 @ 6:00 PM - 8:00 PM



In certain low voltage distributed generation (DG) networks, inverters do not detect unintentional islanding caused by voltage imbalances. This condition violates IEEE-1547 requirements that the networks detect and isolate an island within two seconds of its formation. This paper provides practical application of phase loss detection to inverter protection schemes using transformer networks to address voltage drop considerations. In these applications, phase loss detection can be shielded by the addition of a transformer impedance network, preventing inverter isolation during low
generation conditions. Remote emergency stop initiation via current imbalance detection at the Point of Common Coupling (PCC) can be implemented utilizing a dedicated radio network configured fail safe, providing anti-islanding supplementation to ensure detection. This addition establishes islanding
detection under all generation conditions, improving line worker safety by ensuring power injection removal. Transformer network current analysis is considered for various common transformer configurations, with an existing application example.
