| Abstract: |
| In order to meet the high demand of power supply quality for large capacity and highly sensitive users, a topology structure of cascade H-bridge with energy storage and source-load isolation and a design method of key parameters considering the redundancy of cascade H-bridge are proposed. A set of power supply quality improvement device with the capacity of 1 MV·A for highly sensitive users is developed. Based on power grid simulator, the device performance test platform is built to test the output performance of the device in case of various power supply quality events. The test results show that the proposed topo-logy can automatically realize seamless switching between power grid and energy storage power supply, and provide an effective method for improving the comprehensive power supply quality of highly sensitive users. The proposed parameter design method can reduce the number of energy storage inputs and extend the energy storage life. |
