Islanding detection for distributed generation [PDF]
2005 IEEE Russia Power Tech, 2005 The paper analyzes the performance of a ROCOF relay and looks at the factors that affect its detection capability, such as load type and the impact of load power factors. It also considers how ROCOF can maloperate during system transients. The later section of this paper describes a new LOM detection technique based on a GPS synchronized phasor ...
