变频(VF)发电技术从80年代起在转速范围较小的涡桨飞机上开始广泛应用。变频电源的质量与以往的恒频电源相同,但可靠性高、使用成本低,日益受到人们的青睐。目前这项技术在发电领域已经成为一项工业标准,并经过了成千上万飞行小时的验证。重要的是人们现在对变频电源系统对用电负载的影响已经有了定量的认识
Variable-frequency (VF) power generation technology has been widely used since the 1980s on turboprop aircraft with a smaller speed range. The quality of variable frequency power supply is the same as the constant frequency power supply in the past, but with high reliability and low cost, it is increasingly favored by people. This technology has now become an industry standard in power generation and has been validated by thousands of flight hours. It is important that people now have a quantitative understanding of the impact of the variable frequency power system on the electrical load
