U radu je izvršeno modelovanje i analiza kvaliteta napona u realnoj mreži. Kao primer test mreže korišćena mediteranska obalska mreža. Ona modifikovana dodavanjem dve vetroelektrane. Izvršene su simolicaje radi ztvrđivanja uticaja vetroelektrana na kvalitet Za simulacije korišćen program DIgSILENT PowerFactory.

In the paper protection function setting calculations for elements of transmission system are shown. Analyzed consists 500 kV and 230 voltage levels. The shown several functions reactors, 500/230 kV/kV autotransformers line. Network modeling analysis have been performed using DIgSILENT PowerFactory.

Several industrial-grade power system simulation tools are commercially available on the market. They are expensive to acquire and time-consuming to learn. As a result, very few institutions (utilities, academic/research organizations) can afford to use more than one power system simulation tool. The tools employ slightly different component models, analytical algorithms, and numerical approach...

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...

In the latest research, it has been proven that from point of view losses in a cable distribution line, most advantageous operation is to work with two or one phase metallic screen ungrounded. However, such an may cause changes network characteristics and thus occurrence undesirable phenomena. One those overvoltages screens, which can lead line damage. The simulation tests presented this articl...
