Adjustable Speed

This paper presents a development of measuring device and software for 3-phase measurement of electric power quantities according to IEEE Std. 1459-2010. Blackman-Harris windowed FFT algorithm is used for the harmonic analysis to reduce the errors from leakage problems. Result verification with a technical paper has been made. Actual implementation with an adjustable speed drive at a laboratory has been carried out and crosschecked with a commercial power quality meter.

Quality Indexes

The monitoring results of 6 kV diesel power plant mode parameters are presented in the paper. The diesel power plant supplies the drilling unit of the oil production enterprise. The main goal of the paper is to estimate electric power quality indexes connected with voltage unsinusoidality of the monitored off-grid power system, to compare them with specified in State Standard 32144-2013 [1] and to provide high harmonics reduce methods. The real mode parameters measurements of 3600 kVA diesel power plant in different technological processes connected with oil production were used during the research. The MATLAB software and integrated Fourier transform function were applied to elaborate the mode parameters measurements. Based on harmonic analysis generalized results it is obtained that in many technological processes electric power quality indexes fail to meet the requirements of State Standard 32144-2013 [1]. The filter compensating device with reactive power 1350 kvar installed on 6 kV bus doesn’t allow to supply required electric power quality indexes. The DC drive thyristors rectifiers and the frequency converters of the asynchronous motors of the drill unit parts are the main sources of high harmonics in steady-state modes. The harmonic composition essential changes and electric power quality indexes are reduced due to load power dumps and surges. The high harmonics in such modes are caused by transients in synchronous generators providing supply of the considered power system. The quick-operating electric energy storage system with active power filter function [2] has been proposed as a method to reduce the harmonics.

Voltage Dips

The different power quality phenomena may have characteristics quite different from each other in terms of amplitude, duration, repetition, effects on the system elements, perception of users, etc. Events like interruptions and voltage dips and swells are characterized as phenomena where the root mean square (rms) value of the supply voltage falls below or rises above a prefixed threshold. Description of three-phase measurement device for detecting voltage dips and swells in electric power network is given in this paper. The device has been tested on a real electric power network and practical results of measurement are given.
