摘要：随着可再生能源特别是光伏能源的普及，人们越来越关注电力稳定性，因为大多数分布式发电机（如太阳能逆变器）不具备故障穿越（FRT）能力和无功供电能力（称为动态电压支持（DVS））。日本的电网规范并不需要这些功能。大量光伏发电进入电力系统将恶化未来电力系统的稳定性。本文首先通过简单的仿真展示了带有FRT和DVS的分布式发电机对电力系统电压稳定性的影响。接下来，本文介绍了如何执行太阳能逆变器的这些功能，并说明了 FRT/DVS 与孤岛效应之间的关系。然后，我们在工厂测试中检查了这些方法，并制造了具有 FRT/DVS 功能的 20 kW 太阳能逆变器原型。最后我们在真实电力系统中进行了现场测试，取得了良好的性能。
AbstractWith increasing penetration of renewable energies, especially, photovoltaic energy, more and more concern about power stability will be required because most distributed generators like solar inverters don't have fault ride-through (FRT) capability and reactive power supply capability which is called as dynamic voltage support (DVS). These capabilities haven't been required for a grid code in Japan. Penetration of large amount of PV into power system would deteriorate power system stability in the future. This paper first presents an effect of a distributed generator with FRT and DVS on voltage stability of power system by a simple simulation. Next this paper describes how to perform those capabilities of solar inverter and notes a relation between FRT/DVS and islanding. Then, we examined the methods in a factory test and manufactured a 20-kW prototype of a solar inverter with FRT/DVS capabilities. Finally we performed a field test in real power system, resulting in a good performance.
