| Abstract | ||
| This paper develops a new scheme for accurate and fast response full electronic tap changer. The proposed tap changer uses solid state relays (SSR) for each tap step. The proposed scheme is simulated using Proteus program for a primary design process. Different voltage levels are tested to verify accuracy. The tap changer events could be used as a history in load forecasting studies for substations . A hardware prototype of the proposed OLTC is implemented in this work. Five SSRs operate as the switching taps for 0.5 KVA, 180/110V single phase transformer. The visual basic program is used to monitor and control the voltage regulation process througho ut a personal computer. The simulations and experiments results ensure accuracy and high-speed of the new module ranging between 15 ms to 25 ms for each step change. | ||
