Power System

Providing continuous research for both Power System and Transmission Smart Grid and Wide Area Intelligent Systems to our customers. Pioneer in technology development for wide-area intelligent system in Malaysia, we are committed in providing continuous research for both Power System and Transmission Smart Grid and Wide Area Intelligent Systems to our customers;


  • Coordinated Voltage Control (CVC) System Applications



    With the increasing complexity and interconnectivity of the power grid, the voltage and reactive power (Var) management in the power system operation has become more challenging than ever.


    We conduct studies on the CVC system to provide effective voltage and Var control solutions by coordinating reactive power resources at the transmission system to achieve better voltage profiles and minimize active power losses.


 

  • Real-Time Application Platform (RTAP) System



    RTAP is one of our proven IP inventions, fully optimized in utility substations or control and automation industries.

    Runs on the commercial off-the-shelf computer, RTAP converts data between multiple communication protocols, communicates with any configured and connected devices, performs centralized or local data processing, and executes control commands to multiple control units. Thus, it facilitates advanced system monitoring protection and control.


 

  • Wide Area Monitoring System (WAMS)



    We conduct studies on WAMS to improve the visibility and situational awareness of an extensive power network in real-time.

    By utilizing phasor measurement units (PMUs), information includes GPS time-synchronized magnitude and phase angle of voltage and current, and frequency across the power grids can be monitored and recorded. It enables the power system operators to continuously analyze and improve the knowledge of the network behavior under dynamic conditions.


 

  • Advanced PMU-Based Applications


    Learn our customized solutions for PMU based applications :

    • Adaptive Out-of-Step Protection (AOOSP) provides fast detection of transient instability based on angle difference and quick determination of forced-generator tripping to secure transient stability

    • Real-Time Voltage Stability Margin (RTVSM) offers a scalar magnitude measuring the proximity of the power systems to the voltage collapse point, thus improving the visibility of load margins through aggregated local loads

    • Advanced Overload Protection Scheme (AOLPS) incorporates several key features such as overload protection based on dynamic line rating, conductor temperature calculation, and adaptive load shedding scheme.


 

  • Power System Reliability Studies & Simulations

    Currently, we focus on system planning and improvements of power system reliability and efficiency of existing TNB systems. We use advanced power systems modeling and simulation tools.


    Our ARTPSA performs real-time contingency analysis, screens insecure contingencies, and supplies the power system operators with rapid, effective, and economically sound recommendations for control actions to address transient stability, voltage stability, and thermal security.


    In addition, our ARTPSA studies also offer feasible preventive and enhancement control recommendations to mitigate risk without the need for load shedding and enable an increase in load margins where such margins are judged insufficient. An effective real-time corrective action for critical contingencies is available to increase the load margin by exercising all the following Level-1 control actions: no-cost and low-cost controls before resorting to load shedding.


 

  • Power System Studies Related With Self-Healing Grid

    Our advanced Real-Time Power System Analytics (ARTPSA) provides excellent real-time analytics solutions with the ability to sense, analyze, learn, decide, and respond to any changes in the power grids to ensure continuous compliance with the N-1 criterion.

  • Transmission Smart Grid Applications for Self-Healing Grid



    In this focus area, we conduct studies on enhancing network reliability to ensure the reliability and security of the power supply.


    In general, the self-healing grid will dynamically optimize the performance, automatically anticipating and responding to disturbances, reduce recovery time when unexpected disturbance actually occurs, and continually optimize its performance.
