Abstract

The invention relates to a two-way energy storage converter which comprises a cabinet body (1). An IGBT module (2), a laminated busbar (4), a DC circuit breaker (6) and an AC circuit breaker (7) are arranged on the front side of the cabinet body (1). A DC supporting capacitor (5) is arranged on the rear side of the laminated busbar (4), and an aluminum radiator (3) is arranged on the rear side of the IGBT module (2). An air duct (12) is arranged above the aluminum radiator (3), and a centrifugal air cooler (13), an AC filter capacitor (14) and an integrated transformer (15) are sequentially arranged below the aluminum radiator (3). An AC contactor (8), an AC EMI filter (9), a DC EMI filter (10) and a DC contactor (11) are arranged on the rear side of the cabinet body (1). According to the two-way energy storage converter, the integrated charging and discharging design is adopted, and thus two-way energy flow of the AC system and the DC system can be achieved.

Description

technical field [0001] The invention relates to a bidirectional energy storage converter and belongs to the technical field of power transmission and transformation. Background technique [0002] Because electric energy is difficult to store, in traditional electric power production, power generation, transmission, distribution, and power consumption are carried out almost simultaneously, and the power grid ensures the real-time balance of electric energy through dispatching means. However, under the background of large-scale access to new energy and large-scale development of micro-grids in today's world, due to the instability and discontinuity of the output power of new energy generation, it is easy to cause an imbalance between power supply and demand, which will not only affect power quality, but also cause frequency And the voltage is unstable, and in serious cases, it will cause a power outage, which will bring inconvenience to production and life. [0003] As a powe...
