10kv high voltage switch cabinet energy storage device

What is a high-voltage energy storage system?

A high-voltage energy storage system (ESS) offers a short-term alternative to grid power, enabling consumers to avoid expensive peak power charges or supplement inadequate grid power during high-demand periods. These systems address the increasing gap between energy availability and demand due to the expansion of wind and solar energy generation.

What is the peak value of transient overvoltage at LVDC?

The peak value of transient overvoltage at the LVDC side is about 720 V and overshoot is about 0.02%, and the peak value of transient overcurrent at the LVDC side is about 480 A and overshoot is about 68.4%, which is within the allowable range. Under the condition of 20% rated power, the output current THDi is 3.31%, as shown in Figure 8. Figure 7.

How many kV is a PCs module?

The source drain voltage of the device is V ds = 1.2 kV, and 15 modules are used for each phase in series for 18 kV, meeting the insulation requirements of the 10 kV voltage level. The rated capacity of each module is 23.8 kW, and the rated through current is about 34 A, with a sufficient through current margin. Figure 15. PCS prototype.

Can SiC-MOSFET power devices be used in high-capacity PCs?

Finally, the application of SiC-MOSFET power devices is explored, a 10 kV/1 MW high-capacity PCS prototype is built, and the simulation and experimental results show the feasibility and effectiveness of the proposed topology and control strategy.
