文章导读

随着现有的电力通信专网和公网仍存在覆盖性的不足，尤其广大偏远地区的水电站信息采集业务，其通信覆盖问题尤为突出。卫星通信具有覆盖区域大、适用于多种业务、受地理因素影响小、成本与通信距离无关等优势。本文研究基于高低轨卫星的偏远地区小水电厂站信息采集技术。首先分析偏远地区小水电站信息采集业务需求，然后设计了基于高低轨卫星的偏远地区小水电厂站信息采集系统。针对网络安全防护问题，进一步提出了基于支持向量机算法的网络异常检测技术；通过对偏远地区小水电厂信息采集进行测试验证，结果表明，基于高、低轨混合数据传输系统实现了偏远地区小水电站的信息采集，为计量自动化信息采集系统“全覆盖、全采集、全监测”提供了技术支撑。

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.
