微电网并网验收试验规范的研究

依据现有的国内外相关标准和规范,对验证微电网在并/解列过程以及并网运行中是否满足相关技术要求所必须进行的验收试验进行了研究。结合对微电网并网/解列及并网运行过程中的技术要求,给出了验收试验应具备的条件、测量仪器设备、验收试验的一般流程和验收标准等。重点针对并解列操作、并网运行时的电能质量参数、逆功率保护和短路保护等关键操作、运行参数和保护功能的验收试验进行了设计,给出了相应的测试方法、具体步骤和验收标准。该研究为制定微电网接入验收试验规范提供了较好的基础和依据。

Study on the acceptance test specification of the grid-connected microgrids

According to the current relevant standards and specifications at home and abroad, this paper studies the acceptance tests which must be performed to validate whether the grid-connection/splitting process and grid-connection operation of the Microgrids meet the relevant technical requirements or not. Combining the technical requirements of the Microgrids, this paper gives the conditions, measuring instruments, general process and acceptance standards of the acceptance tests, and focuses on the designing of acceptance tests of key operation, operation parameters and protection functions of the Microgrids, such as grid-connection/splitting process, power quality during the grid-connection operation and reverse power and short-circuit protection, etc. The relevant test methods, specific steps and acceptance standards are proposed. This paper can provide a good foundation and basis for designing the acceptance tests specification of the Microgrids.
