Abstract: Disclosed are a coordinated control method and system for active support of a new energy power station containing a voltage-controlled source. The method includes: obtaining a working mode and a controlled target value of an external characteristic of a new energy power station, and setting internal parameters of a voltage-controlled source and a current-controlled source in the new energy power station; monitoring a power output state of a controlled unit of a voltage source, and calculating a regulation margin of the voltage source; setting power, inertia, and an objective function and a constraint of multi-source coordinated control of primary frequency modulation (FM)/voltage regulation for the new energy power station, and obtaining controlled allocation logic of a current source based on the objective function and the constraint of the multi-source coordinated control; and setting secondary control logic of each controlled unit and its allocation priority strategy.

Abstract: A device for simulating intermittent arc grounding faults in a power distribution network includes a sliding rail, a first and a second support frames, an insulated electrode disk, and an electrode disk motor. The first support frame is fixed on the left side of the slide rail, and the position of the second support frame relative to the first support frame can be adjusted through the sliding rail. The second support frame is provided with an electrode disk motor for driving the insulated electrode disk to rotate. An upper and a lower conductive bars are installed on the first support frame, their adjacent ends provided with an upper and a lower arc-shaped conductor sheets, and the insulated electrode disk having two circles of conductive pillars is located between the conductor sheets. The conductor sheets are respectively installed on the side of the conductive bars close to the conductive pillar.
