装置用途： PWX-50 系列微机消谐装置将微机技术用于电网消谐，利用计算机快速、准确的数据处理能力实现快速傅里叶分析，其选频准确。通过对 PT 开口三角电压的采集，对电网谐振时的各种频率成份能快速分析，准确地辨别出：①单相接地；②过渡过程；③电网谐振。如果是谐振，计算机发出指令使消谐电路投入，实现快速消谐。经实际运行证明本装置对各种高频、低频、工频谐振均判断准确，动作迅速，较完善地解决了电力系统中电网的消谐问题，并能记录存储谐振的次数及谐振频率，可广泛适用于发电厂、变电站及钢铁、煤炭、石油化工等大型厂矿企业的电力系统。 Device USES: PWX - 50 series of harmonic elimination device will computer technology for the power grid harmonic elimination, using computer rapid and accurate data processing ability of the realization of fast Fourier analysis, the frequency selective accurately. Through the collection of PT open delta voltage, the various frequency components of the power grid resonances can be quickly analyzed and accurately identified: single phase ground; The transition process; The grid resonated. If it is a resonance, the computer sends out an instruction to make the harmonic circuit input, the realization of fast dissonance. In practice proved that this device for a variety of high frequency, low frequency and power frequency resonance are accurate, quick, better to solve the problem of the power system harmonic elimination of eccn, and can record store resonant frequency and resonant frequency, can be widely used in power plants, substations, and steel, coal, petrochemical and other large factories and power system.
