Intelligent capacitor and display control method thereof

Abstract

The invention discloses an intelligent capacitor and a display control method thereof. The wiring terminals of the capacitor comprise a UA interface, a UB interface, a UC interface, a current samplinginterface, a network communication interface, an indicator light interface and a UN interface. The UA interfaces, the UB interfaces, the UC interfaces and the UN interfaces of a plurality of capacitors are respectively connected with the Ua interface, the Ub interface, the Uc interface and the Un interface of a controller. Every two adjacent capacitors are connected through a current sampling interface and a network communication interface. After the plurality of capacitors are connected, any capacitor among the plurality of capacitors serves as a main control capacitor. The rest capacitors serve as auxiliary control capacitors, so that a low-voltage reactive automatic control system is formed. If an individual slave fails, switching action is not performed. The rest work is not influenced at all. If a host fails, the rest capacitors automatically generate a new main control capacitor through time sequence competition. Therefore, a new system is formed. Capacitors with the same capacity are switched according to a cyclic switching principle, and capacitors with different capacities are switched according to an adaptive compensation principle.
