Abstract

Power transmission lines play an important role in the distribution of electricity from power to consumers, therefore required effective and reliable protection equipment to maintain the continuity of the provision of electric power. The relays used on the transmission line are Release Relay, Over Current Relay (OCR) and Ground Fault Relay (GFR). Bay 150 kV Srondol - Krapyak is the conductor that will be calculated proteksinya settings The analysis results show that in the high-voltage air channel GI 150 kV Srondol Rele distance as the main safeguard that protects high-voltage air channel Srondol - krapyak with setting (zones and time) with Z1 = 1.764853120 Ω with T1 = 0 s (instant), Z2 = 2.578424893 Ω with T2 = 0.4 s and Z3 = 4,905991928 Ω with T3 = 1.6 s. Overcurrent relay and ground disturbance as reserve safeguard protecting high-voltage air duct Srondol - Krapyak with setting Over current Rele = TMS 0.48 with working time of 1 s, ground noise Rele = TMS 0.63 with 1 s working time. Coordinate the time between the releases of distance as the main safeguard and overcurrent relay, the soil disturbance release as a backup safeguard is appropriate.

Abstract

Electrical power system is an electrical system consisting of generating systems, distribution systems, and power user installation systems. Generating system functions to generate electricity, the distribution system serves to distribute electric power generated from the generating system to the power user installation system, and the power user system serves to supply electrical equipment in order to operate. The demand for electricity increases every one to keep up with population growth and overall economic growth. One important factor to support the development is the electric power that must be fulfilled by the power supply company, in this case is PT. PLN (Persero). The demand for electricity in Java is the largest in Indonesia, because the population of Java Island is predominantly Indonesian, and Java is the center of all economic activities including industry, commerce / business, government and tourism. For that required additional power generation in the future with the planning of power generation system development in Java for the year 2015 - 2024.

Abstract

Three-phase short circuit current at the busbars of 20 kV power transformers 150/20 kV substation is the largest fault current value to be able to cut off the circuit breaker. Breaking current circuit breaker owned by either side of the 150 kV and 20 kV should be able to break the short circuit current is within a certain time. The normal operation of power transformers 150/20 kV substation in a parallel on the side of 150 kV, 20 kV, while the side of each transformer supplying a load busbar respectively. Whereas in certain circumstances the transformer works parallel with the other transformer to supply the load together, short circuit current on the busbar 20 kV become magnified. To reduce that short circuit current on the busbar, then at 20 kV busbar coupling mounted reactor series. This paper will discuss how much value of the reactance of the reactor 20 kV busbar coupling in order to obtain short-circuit current value desired by considering the voltage droop allowed on the busbar.

Abstract

One of the planned areas to be implemented is the construction of a 2x60 MW coal-fired steam power plant in Pulang Pisau District, Central Kalimantan. The development of this steam power plant aims to meet the demand for electricity in Central Kalimantan which has been supplied using barito systems and isolated isolated systems generated from diesel generators. The 80% own barito system is concentrated in South Kalimantan with an electrical interconnection system using 150 KV and 70 KV transmission lines covering South and Central Kalimantan that are connected to hydro, coal and diesel power plants. The other 20% is produced from Central Kalimantan, specifically the capital of Palangkaraya and Katingan regency. Based on the simulation done using DlgSILENT software on barito system after the entry of PLTU Pulang Pisau shows the total change of power supply and the occurrence of voltage changes where the peak load time before PLTU Pulang Pisau enter the total power system generated by 395.18 MW and then after PLTU Pulang Pisau Entered into the total power generation system to 411.14 MW. This value is close to the limit of the operating voltage value but the barito system's transmission rate capability is still sufficient to overcome the change in voltage rise.

Abstract

Generator is an important component of plant. Therefore the reliability and sustainability of a generator in generating electricity depends on the grounding system used. The transformer capacity generated from the calculation of 33.045 kVA in the event of interference. So the capacity of the transformer used must exceed the capacity of the transformer during interruption.

Abstract

The power plant has several components one of which is the Generator and Transformer which become the vital equipment in a power plant. Therefore from the reliability and sustainability of a generator and transformer is very dependent on the protection system used. In this studi discusses the adjustment of differential releases and more currents and coordination of both in the event of interference obtained from the data processing. The value of the adjusting current in the differential releases of 1.75 A with 0.2% mismatch and 6.3 A more current releases and the coordination between the differential releases and the overcurrent is limited by the delay time set on the overcurrent current with the TMS value of 0.159 and The greater the noise current the faster the working time of the relay provides a trip signal to the circuit breaker.

Abstract

At the time a given voltage power transformer there will be symptoms of transient inrush magnetization. This magnetization inrush can cause the magnetization inrush current at power transformer primary coil. This inrush currents perceived as a fault, and therefore at the same time differential relay can not distinguish them from the real fault current, the inrush current will be seen as an internal disorder which should be extinguished. Overcome the inrush current method is to delay, detain or block the relay so that the differential element during transient inrush relay state is not going to work. In this paper will be discussed studies on the effects of inrush current at the differential relay in substation duri kosambi.
