传统的接地故障消弧装置主要处理接地电流中的容性分量，对有功分量和谐波分量的影响很小，限制了其消弧性能。它们所需的电容电流检测精度低，鲁棒性差。常用的大容量无功元件可能与分布的对地电容发生谐振而产生过电压。为了解决这些问题，提出了一种有源接地故障消弧装置。它采用了一种基于单相逆变器的拓扑结构，无需任何大容量电抗器即可将电流注入中性点，从而避免了上述过电压。它补偿接地电流的所有有功、无功和谐波分量，以可靠地熄灭接地故障电弧。提出了一种双闭环电压控制方法，实现了无电容电流检测的消弧功能。它的时基特性也带来了快速响应接地故障电弧抑制的好处。分析了全电流补偿原理，给出了该装置的控制器设计方法。在样机上进行了实验，验证了该装置的有效性。
Traditional ground-fault arc suppression devices mainly deal with capacitive component of ground current and have weak effect on the active and harmonic ones, which limits the arc suppression performance. The capacitive-current detection needed in them suffers from low accuracy and robustness. The commonly used large-capacity reactive component may bring about overvoltage because of possible resonance with the distributed phase-to-ground capacitance. To solve these problems, an active ground-fault arc suppression device is presented. It employs a topology based on a single-phase inverter to inject current into the neutral without any large-capacity reactors, and, thus, avoids the aforementioned overvoltage. It compensates all the active, reactive, and harmonic components of the ground current to reliably extinguish the ground-fault arcs. A dual-loop voltage control method is proposed to realize arc suppression without capacitive-current detection. Its time-based feature also brings the benefit of fast response on ground-fault arc suppression. The principle of full current compensation is analyzed, together with the controller design method of the proposed device. Experiment on a prototype was carried out to validate the effectiveness of the device.
