摘要
随着油田开发的不断深入,油气生产对电力的依赖性越来越强,在油区电网中,由于存在着整流器、变频调速装置、中频加热炉等设备,这些设备产生谐波,造成补偿电容器投不上,甚至跳闸、电容器被烧毁等事故。经对谐波检测分析,采用傅立叶分析及快速傅立叶变换(FFT变换),设计并应用谐波研究治理方案,滤除谐波,改善电压质量,延长了设备使用寿命。
With the deepening development of oilfield,oil and gas production are more and more dependent on electricity.in power net of the oil area,because of the existence of rectifier,frequency control device,intermediate frequency furnace and other equipment,harmonics Capacitor is generated to cause accidents of compensating capacitor not being cast on or even trip and burned.Through analysis for detection of harmonic and by Fourier analysis and fast Fourier transform(FFT transform),harmonic of governance program is designed and applied to filter harmonic wave,improve the voltage quality and extend the service life of equipment.
