PCS system
The energy storage system adopts a 500kW bidirectional converter (with isolation transformer + STS quick transfer switch), which has the basic characteristics of bidirectional inversion, and has a series of special properties and functions, which can realize the charging and discharging functions of the battery system in different applications. The energy storage PCS can be operated automatically, with a high degree of visualization of the operating status, with a display screen as a man-machine interface, and the real-time operation data, real-time fault data, historical fault data, etc. can be clearly displayed through the touch screen or button operation.

Fire control schemes
Fire Protection System Workflow Diagram:


Figure 3-6 Block diagram of the fire extinguishing system

The automatic control and manual control methods of the fire protection system are as follows:
(1) Automatic control
Under normal conditions, the fire protection system is in an automatic control state. When a fire occurs in the battery compartment, the fire detector sends out a fire alarm signal, and the fire alarm controller sends out an audible and light alarm signal, and at the same time sends a linkage command(Turn off air conditioners, fans and other ventilation equipment), issue a fire extinguishing instruction after a delay (at this time, the cabin personnel quickly evacuate), and the alarm host outputs a fire extinguishing signal to drive the container valve solenoid starter, open the container valve on the fire extinguishing agent storage bottle, and release perfluorohexanone to extinguish the fire.
(2) Manual control
When someone is working in the battery compartment, the control mode of the fire alarm controller is manual control, and the fire protection system is in the state of manual control. In the event of a fire, press the start button to activate the fire extinguishing device according to the automatic program. In the case of confirming that all personnel are evacuated, an emergency start device can be used to release the extinguishing agent after the delay to extinguish the fire. In the event of a fire alarm, if it is found that the fire extinguishing system does not need to be activated to extinguish the fire within the delay time, an emergency stop device can be used to terminate the fire extinguishing procedure.
