在我国采油成本中电费一项所占比例较大，而其中游梁式抽油机是用电大户。尽管许多节电措施都有自己的节电效果，但由于其负荷是一个大小和正负方向变化的电功率，很难用普通方法得到正确的计算结果。德国西门子公司的电力系统仿真软件（ＮＥＴＯＭＡＣ）是一个电磁过渡过程的仿真软件。现文利用实测的的运行电流，对游梁式抽油机节电问题进行了仿真研究，给出了电机在正常工作情况下的各电量波形，计算了损耗大小，并提出了用双向可控硅控制线路电流来节电的办法，为今后解决该问题作理论准备。 Electricity costs in our country a large proportion of electricity costs, of which the beam pumping unit is a major electricity users. Although many power-saving measures have their own power-saving effect, but because of its load is a size and positive and negative direction of the change of electric power, it is difficult to get the correct method of calculating the normal results. The German Siemens Power System Simulation Software (NETOMAC) is a simulation of electromagnetic transition process software. In this paper, the actual running current is used to simulate the energy-saving problem of the beam pumping unit. The waveforms of the electrical quantities under normal operating conditions are given, and the losses are calculated. The bidirectional controllable Silicon control circuit current to save electricity for future theoretical solution to the problem.
