In this paper, a disk-line valve top measurement system is introduced. In this system, we use non-contact method to acquire images, and use improved SUSAN arithmetic to inspect image edge. Finally, the image will be yardstick demarcated.
The principle and realization of the active power filter based on DSP are introduced.At the same time,the main circuit and signals detection circuit are also provided.The experimental shows that the system has good dynamic compensation characteristics and has reached the design goals.Also,the harmonic in power system is restrained and the power waves are close to the sine wave.
For the requirements of remote monitoring and nobody on duty,a remote video monitoring system in power substation is discussed.Its basic structure and functional features are described.H.264 protocol is used as the compression way for its better adaptability.The video stream through the TCP/IP protocol and group-broadcast technology is transmitted in real time.
