Information acquisition technology for small hydropower stations in remote areas based on high- and low-orbit satellites

Abstract

With a lack of coverage in private and public power communication networks, especially for collection of information from hydropower stations in remote areas, communication coverage is a significant issue. Satellite communication provides a large coverage area suitable for a variety of services and is less affected by geographical factors; moreover, the costs are independent of the communication distance. This study investigates information acquisition technology for small hydropower stations in remote areas using high- and low-orbit satellites. The information collection needs of small hydropower stations in remote areas are analyzed, and an information acquisition system is designed using high- and low-orbit satellites. For network security protection, network anomaly detection technology based on a support vector machine algorithm is proposed. The effectiveness of information collection was evaluated and verified for small hydropower plants in remote areas. The system provides technical support for “full coverage, full collection, and full monitoring” of the measurement automation information acquisition system.
