The invention discloses a single pole grounding system and a fault detection device and method. According to the single pole grounding system and the fault detection device and method, before the grounding of a normal grounding point, the direct current bus voltages of a system and impedance sampling signals are obtained to calculate the earth impedance of the positive / negative pole of the single pole grounding system, then whether fault grounding points exist is judged, pre-detection before system operation is achieved, and no faults exist before the operation of the system; after the normal grounding points are grounded, whether a grounding fault exists is judged by detecting leaked currents; the grounding pole multipoint grounding fault and non-grounding pole grounding fault which occur during the operation process can be detected when the system is down or the normal grounding points are not grounded through calculating the earth impedance of the positive / negative pole of the single pole grounding system again. Thus, the single pole grounding system and the fault detection device and method achieve the detection on the multipoint grounding fault of the single pole grounding system and the non-grounding pole grounding fault which may occur at the same time.
