The advancement of technology has allowed the exponential development in electric engineering applications, several of these fields are the digital simulation in real- time in conjunction with the synchro-phasor measurements in electrical power systems, the generation of data applying the Montecarlo method and the analysis of data by means of the application of data mining techniques. Research on load-shedding schemes together with the application of the above-mentioned fields allow the prediction of certain events that have caused the disconnection of large amounts of load and even the operating output (blackout) of large power systems around the world. The present project proposes a methodology for the implementation of a load shedding scheme as a function of voltage and frequency that allows, through an indicator, by means of an indicator calculated in real time through a previously trained regressor, to determine the amount of load to be disconnected after the occurrence of a contingency for loss of generation. To do this, a comprehensive real-time digital simulation platform is implemented, which uses the benefits of the OPAL-RT ePHASORsim application, together with the functionalities of CENACE’s WAMS system, WAProtector, to execute a Software in the loop (SIL) oriented to perform adaptive load shedding in real time, which is triggered when the indicator condition calculated by the regressor previously trained with simulation results obtained from PowerFactory is met.

Main focus on:

1. How we used OPAL-RT’s solution in the UPS HIL system design to speed up the product launch.
2. Key parameters Gs Understanding and TSB bridge usage in the UPS HIL system.

Off-shore wind farms are one of important energy sources that realize the carbon neutral before 2050 in Japan. Since the depth of sea around Japan is more that 50m, facilities of transmission systems for off-shore wind farms have to be installed on floating platforms. Middle frequency (500Hz) convertor is a promising equipment that reduce the weight and volume of transformer used for substation on the floating platform. The MMC is a solution that can operate at 500Hz with less switching loss. It however requires much system analysis to develop and tune the control system. Real time simulator is a useful tool for small academic laboratories to study on the MMC. It saves risks of hardware troubles caused by mal operation of control system. An example of studies, such as fundamental operation of scaled model (200V, 1A) of MMC convertor, real time simulation for tuning of control system, and harmonics study in our laboratory will be introduced in the presentation.
