Substation intelligent condition acquisition controller based on IEC61850 for online-monitoring IED

摘要

This paper discusses the condition acquisition controller's realization method based on IEC 61850 standard communication protocol. It presents a design scheme about main structure and key technologies. First, it studied the device's hardware requirements, communication environment, work flow, then designed the device's communication service model and function based on IEC61850 with CMU, provided the interaction logic and the communication process with CAG, the Web access function. Finally, this paper also introduces the method of its implementation. The device is successfully used in smart substation, lay a good foundation for the realization of smart grid's information, automation and interaction.
