| Abstract | Technical praxis has no easy-to-use standardized method for a DC short-current evaluation. For a correct rating of rectifying blocks (diodes) and input and output current-carrying cables is need to know short-current parameters. The current flow in the substation is derived by commutation of rectifying blocks, which define current of transformers and DC part. For evaluating exists a semi empiric formula, that has a delimited relevance to small power range up to 50 kWatts of output power. New way of evaluation of short current is based on simulation of simplified substation model using the capabilities of DYNAST simulation program, or other dynamic equation solver based on numerical method, like Matlab. |
