A review of measurement and analysis of electric power quality on shipboard power system networks

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.

This paper presents an integrated experimental platform of Shipboard Power System (SPS) control system. It was established with equipment of three 100KW diesel generator sets, electric power network, 270KW loads of resistance and inductance, 24KW AC motor drive control system and shipboard automatic power station. The power system and generator sets of experimental platform run under controllers of M340 PLC and PPU. The hardware environment of two layers network is formed for experiments and control programs developing. Field bus and Ethernet technologies are applied for the experimental platform. Combining with some relevant developing software of platform, programs of real time control and electric energy management can be developed and realized for generator sets and electric power network and shipboard power station. Data of SPS experiments can be sampled and recorded in Ethernet computer through sensors, PPU, PLC and Field bus facilities. Also, the functions of SPS characteristic analysis and faults alarming can be implemented by Ethernet computers. This physical experimental platform satisfies the requirements of analysis and research for SPS automatic control.
