Modelling and implementation of intelligent electronic devices (IED)‎ in real-time hardware-in-the-loop (HIL)‎ test system

الملخص EN

Modern power grid utilizes a sophisticated network of Intelligent Electronic Devices (IEDs).

Proper coordination of IEDs is required to ensure safe, reliable and efficient of grid operations.

This paper presents Real-Time Hardware-in-the-Loop (HIL) simulation test system modeled with RT-LAB real-time simulator for the design and testing of TNB Wide Area Defence Plan (WADP) scheme.

The modelling of IEDs, which is one of the crucial components in this HIL test system, equipped with protection, control logics, metering and communication functions is developed.

An overcurrent protection relay based on Inverse-Definite Minimum Time (IDMT) is modelled as key protection element function.

Therefore, the capability of the modelled IEDs in this HIL test system is demonstrated towards the design and testing of TNB WADP scheme.
