“准确的建模不仅对于计划投资，而且对于检测可能导致停电的情况至关重要。使用Mathworks工具，我们可以在一个环境中模拟电源电子，力学和控制系统，我们的模型像我们在现场拥有的涡轮机一样做出反应。”

Hydro-Québec致力于使用可再生能源，主要是水力发电和风能。在将新的风电场在线之前，Hydro-Québec进行了广泛的模拟，以计划将风电场集成到网格中，预测电源输出，并确保整体电力系统的安全，可靠的运行。
Hydro-Québec engineers use Simulink®and Simscape Electrical™建模和模拟单个风力涡轮机和整个风电场。他们使用Simul金宝appink编码器™to generate code, which they incorporate into Hypersim, Hydro-Québec’s multiprocessor simulation environment.
“我们模型控制系统、机器、电力电nics, and measurement systems,” says Richard Gagnon, researcher at Institute de recherche d’Hydro-Québec. “By generating C code from these models, we can use them with Hypersim to study the integration of new wind farms into power system networks.”
挑战
Hydro-Québec must determine how much equipment, such as static VAR compensators (SVCs), will be needed when new wind farms are connected to the power system. “Without accurate models, we risk installing millions of dollars’ worth of unnecessary equipment or not having the equipment we need to meet our reliability and production goals,” says Denis Laurin, manager of technological innovation at Hydro-Québec TransÉnergie.
To obtain accurate simulation results, Hydro-Québec needed to model not only transient stability, which accounts for electromechanical phenomena, but also electromagnetic transients (EMTs). EMT models enable the engineers to understand the dynamic interaction between the electrical modes of the network and the wind power plants.
水量Québec需要对单个涡轮机的控制系统和功率输出进行建模，模拟单个风电场的70-100涡轮机以验证用于建模风电场的聚合方法，然后模拟风电场与电力系统的相互作用网络。
解决方案
Hydro-Québec工程师使用MATLAB建模了单个涡轮机和整个风电场®, Simulink, and Simscape Electrical; generated code from the models with Simulink Coder; and used this code in their multiprocessor environment to evaluate wind farm performance in the context of the power system as a whole.
工程师使用发电机，转换器，电容器，谐波过滤器以及Simscape Electrical金宝app的其他电力电子块在Simulink中构建了风力涡轮机型号。他们还建立了生成器控制系统的模型金宝app模型。
为了研究稳定性，Hydro-Québec使用Simulink中的两种质量系统模型模拟了涡轮机的力学，该模型解释了刀片和扭转效应的音调，除其他细节外。金宝app
Hydro-Québec工程师组装了整个风电场的Simulink型号，金宝app该模型包括73个单独的涡轮机型号和连接它们的收集器网络。
该团队使用S金宝appimulink Coder从其Simulink和Simscape电气模型中生成C代码，并在32过程中的SuperCrouter上在Hydro-Québec的Hypersim模拟环境中运行。
In the resulting real-time environment, the team performed hundreds of simulations with varying operating conditions, wind speeds, and fault scenarios.
The simulation results confirmed that their aggregate wind farm model and the entire wind farm model produced the same voltage and current output at the point of common coupling between the wind farm and the power system.
然后，工程师进行了模拟，其中风电场与电力系统集成在一起，以评估设备需求并评估法规合规性。他们使用了西门子PSS®E软件以验证瞬态稳定性合规性和数学工具，以构建强大而准确的EMT模型。
Hydro-Québec正在使用模拟的结果来指导新风力发电厂的规划，这些发电厂将在其电源系统中增加4,000兆瓦的能力。
结果
Simulation speed increased to real time。劳林说：“以前，完成连接到大型电源系统的涡轮机的直接模拟花费了几个小时。”“现在，我们可以在几秒钟内完成整个风电场的复杂EMT模拟，并获得了连接到同一大型电力系统的总风电场的实时模拟速度。”
Equipment needs accurately predicted。“Using our stability simulation tools with models based on reference Simulink and Simscape Electrical models, we were able to simulate the integration of wind farms into the power system and determine more accurately the amount of dynamic shunt compensation needed,” says Laurin. “When our simulations show that we can reliably operate with just one less SVC, it saves Hydro-Québec millions.”
启用了动态模拟。“With traditional tools, we could not study the interaction between series capacitance and the wind power plant,” notes Gagnon. “The EMT aggregate wind farm models enabled us to perform large-scale power systems studies such as the interaction between series compensation and wind farms.”
