摘　　要：在实验室中很难获得工业现场的负载特性,测功机的出现使该情况有所改善。但受其配套软件功能的限制,很多的负载特性难以用测功机直接模拟。针对这一问题,提出了利用可编程计算机控制器(PCC)控制磁滞测功机实现串行通信加载的方法,并设计了一新型负载特性模拟实验系统。在此基础上,对恒转矩、风机泵类和恒功率3类典型负载特性及三角波负载特性进行了模拟,利用B&R Automation Studio编程软件的TRACE在线监视功能得到了相应的实验曲线。实验结果表明,利用PCC控制磁滞测功机有效地实现了对负载特性的模拟,方法简便,易于实现且精度较高,对实验室中准确获得多种负载特性有较好的指导作用。It is difficult to obtain the actual behavior of load in industrial fields under the laboratory condi- tions. The occurrence of hysteresis absorption dynamometers（HAD） changes the aforementioned situation a lot. But constrained by its affix software, it can＇t be used to simulate certain load characteristics. Aimed at this problem, a method of serial communication loading on HAD which is controlled by PCC（programmable computer controller） was proposed, and a novel experimental system was designed. On the basis of this exper- imental system, four kinds of typical load characteristics were simulated. TRACE the online monitoring function in the B＆R Automation studio software was used to acquire the corresponding experimental curves. The experimental results show that the proposed method effectively implements the simulation of the load charac- teristics, which is simple and accurate to realize, and sounds good to guide the acquirement of the load characteristics under the laboratory conditions.
