This paper presents the implementation of a generic load shedding relay model in a digital real-time simulator (DRTS) that comprises both frequency and voltage based load shedding schemes. The relay model offers three frequency estimation methods, supports multiple load shedding stages and provides a variety of monitoring signals in addition to rel...
Conference Paper
IEC 61850 standard series offers, among other things, convenient and flexible methods of carrying out testing in SASs. Logically isolating IEDs using the simulation feature and monitoring the status of subscriptions for GOOSE and SV communication via dedicated LN classes are two of the most useful features introduced in Edition 2 of IEC 61850 stand...
Conference Paper
Protection systems are increasingly relying on devices that require IEC 61850-9-2/ IEC 61869-9 sampled value (SV) protocol. Non-genuine and non-ideal SV streams could cause protection systems to malfunction and result in serious damage to power system apparatus and lead to cascading failures. SV-based protection functions must be evaluated against...

The current standard for synchrophasors, i.e. IEC/IEEE 60255-118-1:2018, specifies error limits to evaluate electrical performances of phasor measurement units (PMUs). However, the standard specifies neither test plans nor error calculation methods; leading to ambiguities in PMU testing as different test procedures and calculations may produce diff...

Synchrophasors produced by phasor measurement units (PMUs) are widely used in modern power systems for wide-area monitoring, protection and control applications. Contemporary technology allows a PMU to acquire its instantaneous voltage and current inputs digitally from sampled values (SV). This work investigates the electrical performance of two co...

Presentation
High voltage switchgear in an electrical substation can operate in response to either a trip or a switch (opening and closing) command. Typically, protection and control intelligent electronic devices (IEDs) at bay level possess the authority to issue trip commands to circuit breakers, which are directly communicated and often carried out without d...

A microgrid is a portion of a distribution network and is commonly designed to operate in parallel with the power grid or autonomously as a power island. Therefore, islanding detection is one of the key aspects of grid connected microgrids. In literature, performances of islanding detection methods are largely tested with offline simulation tools a...
