基于Digsilent的风电场保护研究 Introduction:Digsilent is a powerful and versatile power system analysis software used by power system engineers throughout the world. It is a comprehensive software, which simplifies the process of modeling, analyzing, and simulating complex electrical systems. Amongst the many applications of Digsilent, one of the most important is its use in the analysis of wind power. This paper aims to provide an overview of Digsilent's wind power analysis capabilities with specific emphasis on wind farm protection.Wind Farm ProtectionWind farms, like any other electrical system, need protection to ensure their safe and reliable operation. They are complex systems consisting of numerous turbines, switchgear, transformers, and other electrical equipment. All of these need to work in sync for the wind farm to deliver its maximum power output while ensuring the safety of the equipment and personnel working on the site.When designing a wind power protection system, the following factors must be considered:1. The type and size of the wind turbines2. The voltage level of the wind farm3. The location of the wind farm (onshore or offshore)4. The interconnection with the grid5. The available safety standards and regulations.Digsilent's capabilitiesDigsilent offers a comprehensive range of tools and models to simulate and analyze the behavior of the wind farm protection system in different scenarios. The following are some of the key features of Digsilent:1. Fault simulation: Digsilent allows modeling of different types of faults that can occur in a wind farm, including single-phase faults, phase-to-phase faults, phase-to-ground faults, and others. The software calculates the fault current levels and the behavior of the protection system.2. Relay coordination: Digsilent's relay coordination feature can be used to assess the performance of the protection relays in coordination with one another. The software can identify any potential conflicts
