Sažetak
The electrical power system provides production and delivery of electrical energy in sufficient quantities to areas that need electricity through a grid. The goal of the electrical power system is a secure and reliable electricity supply of costumers at minimum costs. Due to its complexity and stochastic nature, the electric power system is exposed to disturbances and faults. For those reasons it is necessary to continuously measure and analyze power quality parameters in key points of the electric power system. In this paper, power quality analysis on the 400 kV interconnected transmission line is performed according to the “Croatian grid code”. Measuring is provided for one week at a resolution of 10 minutes. The analysis includes observation of voltage and frequency variation along with amounts of total harmonic distortion (THD) and amounts of short term (Pst) and long term (Plt) severity flickers. Measuring is performed with the power quality analyzer “Dranetz – BMI Power Explorer PX5”. The obtained results are compared with limits determined by the Croatian grid code.
