考虑到太阳能光伏发电具有波动性、间歇性、随机性的固有特征,各国电网运营商均针对光伏发电系统的并网性能提出技术要求。由于光伏发电站电气条件、地理位置及测试装置容量等限制因素,其系统的并网性能往往无法直接测量,难以验证是否满足标准要求。因此,德国能源与水行业协会(BDEW)标准《Generating plants connected to the medium-voltage network》不但要求光伏逆变器通过实验室的型式试验,且需提供与实测结果一致的仿真模型用于系统并网性能的分析与评价。依据BDEW标准,基于DIgSILENT仿真平台开展光伏并网逆变器建模仿真,分析计算实测与仿真的数据误差,开发模型验证工具,评判光伏并网逆变器模型是否满足标准验证要求,以解决光伏逆变器模型的准确性无法有效衡量的问题,为开展光伏发电站接入电网的分析提供基础。 相似文献

Well, the November/December issue of the magazine seems to be a Color Books update issue, since I provided a similar update called "What's Happening to the Color Books?" last year. That's OK. Because it gives me an opportunity to keep you informed about one of the most significant changes in IAS Standards development in several decades. 相似文献

The IEEE standards-making process is organized through the IEEE Standards Association (IEEE-SA) and the IEEE-SA Standards Board. Because standards have legal implications, there are rules and guidelines that we are obliged to follow in the process of standards development. 相似文献

This is an introduction to international standards and describes two global organizations, CIGRE and IEC. CIGRE is important to the manufacturers of electrical power equipment and electrical utilities. It often carries out the preliminary work needed for high-voltage international standards prepared by the IEC. IEC prepares standards on all aspects of electrical equipment and electronics. 相似文献
