摘要
研究了逆变器的实际性能，主要集中在谐波失真和功率因数上。审查中的逆变器在价格和设备质量方面代表了英国市场的横截面。它们包括电压源和电流源转换器拓扑结构。将测试结果与英国BS EN 61000-3-2电磁兼容性标准的相关条款和工程建议G83/1的相关条款进行比较。考虑了直流耦合储能对单个系统的附加影响。部分负载性能的影响进行了评估。在逆变器接口分布式发电的高渗透率普遍存在的未来网络中，对现行标准的持续适用性提出了关注。
Power quality observations for solar photovoltaic inverters under part-load operation
The real-world performance of inverters is investigated across their full range of operation, concentrating on harmonic distortion and power factor. The inverters under review are representative of a cross-section of the UK market in terms of price and device quality. They include both voltage and current source converter topologies. The test results are compared against the relevant clauses of the BS EN 61000-3-2 standard for electromagnetic compatibility and those of Engineering Recommendation G83/1, for the UK. The additional impact of DC coupled energy storage on one system is considered. The implications of part-load performance are evaluated. Concerns are raised regarding the ongoing applicability of prevailing standards within future networks in which high penetrations of inverter-interfaced distributed generation are prevalent.
