摘要
Abstract
Based on the requirement of the dispatching center of Southern Power Grid that the sub-station can receive the plan curve of the setting day and have the function of curve check, according to the situation ofIEC60870-5-104 protocol that it lacks definition of the curve ASDU type, we do some extended research on 104 protocol application. This paper proposes the idea of“inflection point”and gives the judge strategy and calculation methods. The research has been implied in project based on NC2000 system(NARI monitoring and control system). We resolve the problem of automatically call of daily curve of different days based on the platform support, and realize the functions of curve display, curve receiving and curve check, guarantee the safety and accuracy of curve issue,and satisfy the project needs. Currently, this system has been put into practice in many hydropower plants, and shows good stability and accuracy.关键词
