Connection of 8 MW CHP to belgrade distribution grid

摘要

A connection of perspective 8 MW power plant Umka to 10 kV power distribution grid in Belgrade is presented in the paper. The connection is specific about two aspects: 8 MW is high power to be evacuated over 10 kV grid and power plant will be connected to 10 kV directly, without step-up transformer. Short circuits and load flow system analyses are carried out by using the computer simulation models of distribution system critical operation regimes in order to investigate connection criteria defined by distribution system grid code. Another contribution of power plant Umka should be strengthening of 10 kV distribution grid and elimination of voltage dips problems that have occurred for years in a factory Umka.
