| Abstract: |
| As the operating parameters of 10 kV power system for railway vary quickly and the transmission and processing of massive data are much tough，the SCADA system with synchronous real-time data transmission is developed. The remote transmission of operational data and recorded data is analyzed and the processing of massive real-time data is designed. The asynchronous transmission of real-time data is proposed based on the publisher ／ subscriber principle and two-level caching mechanism is established to guarantee information integrity and avoid important information loss. The developed system operates stably and reliably，with better real-time performance. |
