Abstract: This paper studies the mine electric power equipment monitoring system based on Hadoop, proposes electricity parameter calculation method and the algorithm of time series prediction based on ARMA model, designs and realizes a kind of specially designed integrated protection system for coal mine involves relay protection, measurement and control, data communication, analysis and prediction of historical data. The experimental results show that the system is an effective and practical, strong expansibility and easy deployment of mine power equipment monitoring system.

Key words: Hadoop, power protection, electric power parameter monitoring, ARMA model
