摘要
电力系统无功补偿可以提高发供电设备输送有功功率的能力,改善电压质量,降低线路损失。新兴的DSP较传统的单片机控制在准确性和实时性上有较大提高,但涉及到上位机通讯,存储历史资料,控制界面等方面有不足之处。本文详细介绍了基于Lab VIEW的静止无功发生器,能克服上述不足。该系统利用PC的CPU处理实时数据,可使用各种复杂算法,且速度快;利用HD存储历史资料,容量大;利用Lab VIEW设计的控制界面,直观、大方;而且可实现多路监控,提高资源利用效率。
In the electrical power system reactive power Compensation can enhance efficiency when generating and supplying plant transporting the active power, improve voltage quality, and reduce the lose of the line. DSP technology has more superior performance in accuracy and real-time Performance in comparison with the conventional single chip microcomputer but it is still insufficient in terms of upper MCU Communication, history document storage, and control interface etc. A SVG device based on LabVIEW proposed here can overcome above shortcomings. Fast calculating ability of CPU in PC enable high complex real-time data processing algorithm be realized and high speed be achieved, HD memory history material enlarged the storage capacity, and LabVIEW designing control interface brings directviewing and natural feeling for users. Moreover this system can also capable of the multi-channel monitoring and enhancing resources using efficiency.
