The paper deals with designing and implementation of Smart Grid with designing of power quality measurement software in these networks. Various renewable sources represented by small hydropower plant, photovoltaic power plant and wind power plant are integrated in the designed scheme of Smart Grid. A part of the real network model in laboratory environment is controlling and evaluating SCADA system...
The problem of modeling electrical loads in the calculation of modes of electric networks with controllable arc extinguish reactor with asymmetry modes is considered. The model is based on the simplifying assumption of constant power load permitting the use of a minimum set of input data. The equations are obtained using methods of phase coordinates and symmetrical components. The model is a formula...
This paper discusses universal methodology for quantification of equipment trips due to voltage sags. Every sensitive equipment is described by the voltage-tolerance curve with specific limit values. Generally, one type of the sensitive equipment can be described by different characteristics that create an area of uncertainty, which influences the behavior of these devices. For calculation of expected...
