Intelligent flexible super power supply

In view of the seasonal short-time overload, three-phase imbalance, unbalanced reactive power compensation and other problems of the transformer in the distribution station area, as well as the cost, noise, serious environmental pollution, startup time and other problems of the traditional emergency power protection system, our company has launched the intelligent flexible super power supply.
The system adopts the high power density lithium iron phosphate battery as the energy storage element, which is composed of special energy storage battery, special energy storage PACK, battery management system (BMS), energy storage series converter (PCS) and other systems. In combination with the actual situation and demand, two specifications of 120kW/225kWh and 240kW/450kWh were introduced to support the parallel expansion of multiple groups of systems.
The system uses intelligent string energy storage to solve the problem. The new design concept has three advantages: string, intelligence, modularization. According to different response scenarios, parallel and series connection modes are adopted. Parallel connection of distribution transformer can realize dynamic capacity increase of distribution transformer, solve three-phase unbalance, realize reactive power compensation, and be suitable for distribution station area and other occasions; The series connection of power supply can realize millisecond emergency power supply and power quality control, and is suitable for important power supply occasions such as important conferences and sports events.
