传统上，离线建模和仿真一直是改善风能系统控制策略及其公用事业系统集成的首选工具。本文探讨了如何建立一个新的实时硬件在环（HIL）测试设备，设计用于测试全电动船舶推进系统，可以用于风能研究。测试现场使用两台2.5 MW/220 rpm测功机和一台5 MW可变电压和频率转换器，以模拟真实的动态环境，包括机械和电气。该设施由数字实时电力系统仿真器（RTDS）控制，该仿真器能够模拟相当复杂的电网和控制系统，通常具有50微秒的时间步长。大量的I/O允许将测量的量反馈到模拟中。一个15千瓦的模拟电动发电机组被用来证明一些关键方面的概念。从动态测试结果可以得出结论，该系统显示出巨大的潜力，开发一个独一无二的风能研究平台。
Traditionally, off-line modeling and simulation has been the tool of choice for improving wind energy system control strategies their utility system integration. This paper exploits how a newly established real-time hardware-in-loop (HIL) test facility, designed for testing all-electric ship propulsion systems, can be utilized for wind energy research. The test site uses two 2.5 MW/220 rpm dynamometers and a 5 MW variable voltage and frequency converter to emulate a realistic dynamic environment, both mechanically and electrically. The facility is controlled by a digital real-time electric power system simulator (RTDS), capable of simulating electrical networks and control systems of substantial complexity, typically with 50 microseconds time step. Substantial I/O allows the feedback of measured quantities into the simulation. A 15 kW mock-up motor-generator set is used to demonstrate some critical aspects of the concept. From dynamic test results presented it is concluded that the proposed system shows great potential for development of a one-of-a-kind wind energy research platform.
