The continuous verification of performance indicators and the minimum technical requirements required by regulation electricity sector aim to list conditions that may affect operation electric power system its equipment. factor, although monitored in steady state, provides an increase electromagnetic transients due switching capacitor banks with objective providing adequacy value range. In this...

The renewable hybrid energy system may be quite an that uses the same infrastructure. Although structures are fed from different types of sources, they systems give to grid over busbar and transmission line. amount can deliver is limited by installed capacity main source. A well-designed produce more stable electricity throughout year. advanced technology networks various sources guarantee very...

In this study, genetic programming (GP) is used for optimizing bus and line separation methods to reduce the short-circuit current. Expanding power systems led intensive electric more transmission lines, reducing grid impedance. This increases currents that occur during failure, it impossible continue developing higher-capacity breakers accommodate such currents. Therefore, must be managed syst...

Modeling of electromagnetic wave propagation inside a gas-insulated switchgear structure can be helpful for understanding and improving the utilization partial discharge detection by providing information to help determine more optimal positioning ultra-high frequency sensors. This paper studies effect insulating spacers, L- T-type structures on simulating time dependent behavior these arrangem...

On the basis of National Research University "MPEI", within framework project to create a busbar with polymer-gas insulation for transmission electricity from offshore wind turbines, study is being carried out develop insulating structures high-voltage busbars. The work devoted development and justification design special conductor combined (polymer-gas) laying in sea water electrical energy wh...

This article presents a novel deterministic methodology to determine the maximum distributed generation capacity in power distribution systems. In proposed approach, an optimization problem is formulated calculate amount of be accommodated system without violating operational limits. For formulation, current injection method equations are considered as equality constraints compute flow solution...

Jaringan power listrik kapal untuk kegiatan operasional pelayaran memiliki karakteristik 3 phase 450 VAC 60 Hz, sumber diproduksi generator dengan kapasitas 562 KVA. Gangguan pada jaringan adalah undervoltage dan overvoltage, kondisi ini menyebabkan terjadinya voltage collapse atau blackout. Voltage tidak boleh terjadi sistem power, karena itu banyak penelitian terdahulu membahas berusaha menga...

The electrical quality, especially voltage fluctuations, is very important to remain stable in supplying consumers. PT. PLN (Persero) has a minimum limit of -5% and maximum +10% which regulated the Minister Energy Mineral Resources no. 3 2007 transmission system. However, 150 KV system often experiences drops caused by conductors that are too long inappropriate loads, so maintaining good reliab...
