Harmonic Analysis And Management Of Oilfield Distribution Network

Since 1980's, power electronics has become an emerging cross-marginal science, and this corresponds to the modern power electronic technology has been developing rapidly. However, due to power electronic devices is a nonlinear time-varying topology load, caused by harmonic pollution on power system security, stability, economic operation constitutes a potential threat to the electrical environment around a great impact, is recognized as Power of a public hazard.With oil production and oil field workers to improve the living standards of families, a number of non-linear and time-varying components more and more appear in the field grid, or expressed as an increasing number of such loads, more and more run-time focus on the impact of the grid field is also growing.In this paper, the common measure index of power quality, harmonic generation and harmfulness, as well as the harmonic content standard has been analyzed in detail. This paper also introduced the common methods of harmonic suppression, and analyzed the working principle of active power filter and its system structure. This paper mainly studied the harmonic current detection method, as well as the analysis and suppression of harmonic. On this basis, this paper first identified the harmonic sources and their geographical distribution of Southern P1 618 line distribution network in Zhongyuan oilfield, thus to make out the monitoring points and harmonic control standards. Then this paper has chosen the power harmonic active filter that of appropriate type for harmonic suppression on the basis of detailed analysis of harmonic components.
