The application provides a multifunctional static synchronous compensator system, comprising: a plurality of three-phase converter valves, input ends of each three-phase converter valve being connected to a common DC bus; an energy storage valve, being connected in parallel with the three-phase converter valve, and the plurality of three-phase converter valves sharing the energy storage valve through the common DC bus; a switch breaker device, being arranged between the three-phase converter valve and the energy storage valve; and a control unit, being connected with the plurality of three-phase converter valves, the energy storage valve and the switch breaker device respectively. The application also provides a method for operating the multifunctional static synchronous compensator system. The multifunctional static synchronous compensator system provided by the application adopts back-to-back converter valves, shares energy storage elements through a common DC bus, and connects two AC buses to the two sides of the converter valve, so that the system can support the two AC power grids, greatly save the installation capacity of the energy storage elements in the energy storage valve, and provide power interconnection between the two AC power grids and play a role in tidal flow control.

This invention discloses a zero-energy building composite insulation board, comprising an outer insulation board, a first substrate, a second substrate, a flat heat pipe array, a heat source, and a flat heat pipe array tilt adjustment system. The second substrate is fixed to the outer insulation board. The flat heat pipe array tilt adjustment system controls the rotation angle of the parallel heat pipe array and is installed between the first and second substrates. The heat source is installed on either the first or second substrate, and the outer insulation board is fixed to the outside of the first substrate. This zero-energy building composite insulation board is less affected by the building construction stage, has a simple installation process, and is suitable for both new buildings and energy-saving renovations of existing buildings, showing great potential for application and promotion.

This invention provides an induction heating cluster device, relating to the field of induction heating technology, including an induction heating power supply, an induction heating device group, and a smart terminal.
