IEC 61660-1기반 직류배전시스템의 단락전류 검토

We investigated a short-circuit current for DC distribution system based on the IEC 61660-1. Short-circuit currents of DC distribution system are addition of four partial short-circuit currents which are rectifiers in three-phase AC bridge connection, stationary batteries, smoothing capacitors, DC motors. Each of four partial short-circuit current be calculated by standard approximation function.
