摘要
针对变压器在抽油机起动时所需容量大,而正常运行时所需容量小这一现象,提出了可实现有载调容的变压器。应用时域—频域法建立了有载调容变压器的磁路与电路模型,并进行了计算仿真及应用。结果表明:有载调容变压器可实现有载调容,降低了空载损耗、负载损耗、电网占有率和网损,提高了电网的功率因数,可节省大量增容费和运行费。
This paper puts forward a kind of regulated capacity transformer which supplies the biggest power capacity while oil pump is starting to move and which supplies smaller power capacity with oil pump moving smoothly. Applying time domain and frequency domain method to calculate transformer's circuit model and magnetic circuit model by simulation, a conclusion is reached that regulated capacity transformer can regulate supply capacity on load and reduce loss without load, loss with load and electrified wire netting loss, increase electrified wire netting power factor, cut down a lot of capacity-bulking cost and operating cost.
