摘要

本文提出了一种能够实现光伏逆变器快速仿真的插值方法。插值方法基于事件驱动的插值方法，可以在仿真模型中引入事件驱动的插值方法，以在保持精度的同时以更高的时间步长运行模型。所提出的方法在中性点钳位(NPC)转换器和双电平转换器(2LC)上进行了测试，这两种转换器通常用于大型光伏电站。将插值方法集成到PSCAD/Fortran和RSCAD C平台的NPC和2LC仿真模型中。这些模型分别在离线仿真平台PSCAD和实时仿真平台RSCAD上进行了不同时间步长的仿真测试。

Interpolation Methods to Enable Fast and Accurate EMT Simulation of PV Inverters

In this paper, interpolation methods to enable fast simulation of photovoltaic (PV) inverters are proposed. The interpolation methods are based on the event-driven interpolating method that can be introduced in the simulation model to run the model at a higher timestep while maintaining accuracy. The proposed methods are tested on a neutral point clamp (NPC) converter and a two-level converter (2LC) that are typically used in large-scale PV plants. The interpolation methods are integrated into the NPC and 2LC simulation models in PSCAD/Fortran and RSCAD C platforms. These models are tested at different simulation timesteps in off-line and real-time simulation platforms PSCAD and RSCAD respectively.

期刊介绍： COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
