Abstract

In the recent decade, there has been a rising concern about energy consumption and environmental issues. This trend has shifted the focus of electric utility from fossil fuels to renewable energy. Thus, distributed generation (DG) that generated power from renewable energy sources has been on the rise. However, the presence of DG can affect the operation of power system protection and may cause a technical issue with the equipment. So, this paper investigates the impacts of wind power-based DG installed on the distribution system in Thailand using PSCAD software. The case study system is modeled after part of the Provincial Electricity Authority (PEA) distribution network in Northern Thailand. The comparative study with the case without DG has also been done on various parameters such as type of faults, location, and number of DG. The result from a study reveals the impact of DG on the distribution system characteristics, which changing drastically. Thus, an analysis of the impact of DG on the system must be done to address its effects and ensure the reliability of the power system.

配电系统故障时多风分布式发电机位置的影响

近十年来，人们越来越关注能源消耗和环境问题。这一趋势使电力公司的重点从化石燃料转向可再生能源。因此，利用可再生能源发电的分布式发电(DG)正在兴起。然而，DG的存在会影响电力系统保护的运行，并可能导致设备的技术问题。因此，本文利用PSCAD软件研究了风电DG安装对泰国配电系统的影响。该案例研究系统以泰国北部省电力局(PEA)配电网络的一部分为模型。并对故障类型、位置、DG数量等参数与无DG情况进行了对比研究。研究结果揭示了DG对配电系统特性的影响，这些特性发生了巨大的变化。因此，必须对DG对系统的影响进行分析，以解决其影响并确保电力系统的可靠性。
