Parallel contingency analysis solution based on OpenMP

Cirata subsystem is part of the 150 kV interconnection system 150 kV West Java which is supplied by two units of IBT 500/150 kV with a power capacity of each IBT is 500 MVA. It has 15 transmission line connecting the substation 13 (GI), while the generation units that exist in the subsystem Cirata is PLTP Patuha with a power of 55 MW and 180 MW hydropower Jatiluhur. The reliability of the power system must be maintained in order to supply power from the generator to the consumer to keep going well. At peak load conditions and contingencies, an electric power system will undergo changes in value, both current and voltage. In this study, which analyzed disorder is a contingency (N-2), a discharge of the two components of transmission line system and generator. The aim is to evaluate and improve the reliability of electric power systems of 150 kV Subsystem Cirata, analyzing the effects of disturbance contingency (N-2) to changes in current and voltage, identify the bus voltage is outside the operating limits, identifying the transmission line that experienced the imposition of critical / exceeds limit operation, and perform load shedding (load sheeding) to overcome the weaknesses of the power system due to disruption contingency N-2. The study was conducted by collecting data required for power flow simulation using Newton-Raphson method in ETAP 12.6.0. The simulation results show the power flow interruption due to voltage profile under the standard contingency SPLN 150 kV + 5% and -10%, and becomes critical channel loading over 50% of the nominal current conductor. While after the release of the load (load sheeding) voltage profile in Subsystem Cirata back normal or standardized SPLN and loading the channel becomes lighter.
