Experimental determination of static characteristics of loads in nodes of a 6 kv power supply system

Abstract

Subject of research: static characteristics of nodes of 6 kV power supply systems with asynchronous load. Purpose of research: experimental determination of static characteristics by active and reactive power, calculation of the reserve coefficient by static stability of a node with asynchronous load. Object of research: power supply systems with a complex load, which includes asynchronous motors. Main results of research: the results of an active experiment to determine the static characteristics of the load node are presented. The measurements were carried out using devices that record the quality of electricity. Voltage regulation was carried out by the RPN device, the current transformers on the input switch were selected as the connection point of the device. Static characteristics of active and reactive power were constructed using interpolation and extrapolation tools. The critical voltage of the load node is determined. The coefficient of static stability margin is determined.
