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...
Conference Paper
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...

Full-text available
IEC 61850 has become the preferred standard for substation automation for many utilities around the world. However, its provisions to automate control systems in a substation remain a lesser-discussed topic of the IEC 61850 standard series. Testing and validation of control systems in an electrical substation such as high voltage switchgear control...

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...

Many commercial phasor measurement units (PMUs) extract phasors using the standard discrete Fourier transform (DFT) that has some inherent drawbacks such as leakage and picket fence effects. The standard DFT based PMUs employ additional filtering to overcome these effects, but the smart DFT (SDFT) algorithm is capable achieving the required accurac...
Conference Paper
The rapid advance of synchrophasor technology and the growth of phasor measurement unit (PMU) installations in the recent years have substantially increased the feasibility of deploying practical synchrophasor applications. These novel applications need to be thoroughly evaluated before their actual implementations on real power systems. The most f...

Reliable operation of power systems requires detailed models of the network during system studies. Transmission line parameters are essential for accurate simulation results as many of power system studies depend upon the precision of transmission line parameters. In this paper, a noise adaptable synchrophasor based real-time parameters monitoring...
Presentation
Currently, synchrophasor measurement technology is primarily used for monitoring applications; however, its potential for use in stability enhancement, especially transient stability status prediction is not fully utilized. Synchrophasor measurements, when combined with advanced telecommunication infrastructure, enables real-time observation of the...

Testing of Phasor Measurement Units (PMU devices) is necessary for any PMU application, be it a simple visualization and archiving system or a more complex set of real-time system operations tools. PMUs are available from virtually every manufacturer of protection and monitoring equipment. PMUs can be an embedded function within relays or disturban...
Conference Paper
This paper addresses three aspects of testing relay protection systems using a real time simulator: (1) simplify the setup by using low level analog signals to the relay; (2) use a ‘threading’ process when a hybrid setup (commercial relays and simulated relay models) is chosen; (3) test substation protection system together with control and communi...

Conference Paper
Testing IEC 61850 devices is a critical part of any substation automation scheme. Many IEDs have been installed and configured to provide status and control via GOOSE messages. IEDs can also be configured to listen to sampled value data. An important part of IEC 61850 data being transmitted can be the test and quality information. Real time digital...
Conference Paper
This paper utilizes a significantly improved phase domain synchronous machine model [3] to test a multi-function relay model created for a real time digital simulator. One of the features of the machine model is its capability of simulating stator internal faults. Third harmonic voltage on the neutral and terminals of the machine and its variation...
Conference Paper
By default, a real time digital simulator will execute a simulation case and provide the solution for the controls and power system every time-step (typically 50 musec). The length of the time step is decided by the time taken to execute the longest component algorithm. The component in question may be that for a protective relay which takes in new...
Conference Paper
Removal of a single line to ground fault by isolating only the faulted phase frequently leads to the creation of a secondary fault arc. Auto reclose protection schemes depend upon the absence of a secondary arc prior to reclosing. Consequently, there is great benefit from a technology to determine secondary arc extinction detection. The testing of...
