Simulation Eliminates Surprises

Electrical network simulations have traditionally been using phasor domain simulation to determine load flow, voltage profile and fault levels in an electrical network. With the increasing use of renewable energy, FACTS and distributed generation, phasor domain simulations cannot capture the rapid responses of the FACTS equipment and therefore time domain simulations needed to be used for study of the modern power system.

Time domain simulations can be carried out in the offline mode or real time mode. There are a number of industrial standard time-domain simulation software available which are based mainly on the Electro Magnetic Transient Program(EMTP) developed by Dr. Hermann Dommel of Bonneville Power Administration in 1966. The prominent commercial software packages are PSCAD, EMTP-RV and the original EMTP software package. These software has utilized the power of modern computers to enable simulations of thousands of buses in a reasonable time frame. This has made the use of time domain simulations in a large network possible for the study of traditional electrical network system studies as well as transient studies and system stability studies.

An offline EMTP simulation can be brought online and carry out the simulation in real-time or very near real time. The time step of such a simulation would be in the range of tens of micro-seconds which is considered in the fraternity as near enough to real-time. With the real time simulators such as OPAL-RT and RTDS, real-time simulations can be carried out for large systems under studies. Power system modelling primarily uses EMTP software packages described above while other field of engineering utilizes Matlab and Matlab Simulink for modelling. Real time simulations is not limited to the electrical system but also in any other closed loop systems which can be modelled in Matlab.

About Us

Electrical System Studies and HIL Simulation

BSRLab Sdn. Bhd. was established in 2019 in Kuching, Sarawak, Malaysia. The primary objective of BSRLab is to carry out electrical network modeling and simulation using real-time and offline EMTP tools. BSRLab is collaborating with University of Malaysia Sarawak(UNIMAS) to exchange tecnical knowledge and industrial experience. BSRLab is also sponsoring postgraduate students as part of our CSR.

BSRLab uses OPAL-RT to carry out real-time simulation of electrical network enabling the testing and verification of device schemes, settings, operational philosophy and device programmed I/O maps. In this hardware-in-the-loop(HIL) setup, the inputs are generated by the real-time simulator and outputs from the devices are monitored by the simulator in a closed loop configuration. Results are recorded and analysed to ascertain that the final setup meets specifications and functional requirements

Offline simulation using EMTP software to study transient over-voltages in the system to determine critical parameters required for substation equipment, insulation coordination studies, root cause analysis and recreation of fault events.

Our Services

We provide on-time and on-budget professional services

Hardware in the Loop

HIL is a very effective way to to test any physical device connected to the system and observe the output of multiple test scenarios. The results can be verified against design and operational criteria.

Generator Modeling

We work with VI Consulting to carry out generator modelling for system stability studies for software such as PSSe and DSAT tools.

System Impact Studies

We work with VI Consulting to carry out SIS as required by legal requirement for large power consumers(above 30MW) as well as planting of generation connecting to the grid system.

Protection Setting

Protection relay settings study is required to ensure proper discrimination and shortest tripping time to clear the fault. We provide system wide protection studies verified by CAPE software for MV to EHV systems.
