摘要（英）：

The invention provides an intelligent RLC (resistance inductance capacitance) load and island-preventing detecting unit which comprises a direct current power source, an inverter, switch units, an RLC adjustable load unit, a waveform recorder, a power grid and an ADAM controller. One side of the inverter is connected with the direct current power source, and the other side thereof is connected with the RLC adjustable load unit and the power grid in parallel. The waveform recorder tests current waveforms of the inverter and the power grid respectively. The switch units are arranged on conductive paths of the inverter, the RLC adjustable load unit and the power grid. The ADAM controller controls the switch units. The intelligent RLC load and island-preventing detecting circuit is capable of accurately detecting island-preventing function of a grid power source of a user side and can meet the technical requirements of standard regulations such as VDE-0126 and IEC62116.
