| Abstract: |
| The HW structure and SW simulation of the DSP based digital test equipment for protection relays are introduced. It takes the advantage of DSP in digital signal processing, and plants the simulation model and algorithm of electric power system into DSP. With the flexible MMI,the equipment can quickly, freely and accurately simulate the actual dynamic process of a power system fault by the simulated current and voltage at the relay position. It provides a powerful tool for testing protection relay. |
