Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0024] The dynamic migration of the measurement and control device is to realize that the cluster measurement and control device has the same two sets of measurement and control functions running on the same interval at any time. On another set of spare cluster measurement and control devices. figure 1 A schematic diagram of the dynamic migration of the measurement and control device is shown. From figure 1 It can be s...

Abstract

The invention discloses a dynamic migration method of cluster measurement and control devices. Functional migration modes between the two sets of cluster measurement and control devices comprise a manual switching mode and an automatic switching mode. In the manual switching mode, function switching between double sets of cluster measurement and control is realized by manually switching each softpressing plate. In the automatic migration mode, the online state is judged by monitoring heartbeat messages of a station control layer in parallel, and function switching between double sets of cluster measurement and control is achieved. According to the method, the problem of function loss when the device fails and the equipment is abnormal is avoided, the reliability of operation state switching and dynamic migration of the logic measurement and control unit is effectively ensured, the effectiveness and continuity of data acquisition are ensured, and the safety of a transformer substationmonitoring system is improved.

Description

technical field [0001] The invention relates to the technical measurement and control field of electric equipment, in particular to a dynamic migration method of a cluster measurement and control device. Background technique [0002] After the start of the construction of smart substations, due to the lag of standard technical specifications, conflicting technologies and functions between different standards, and system problems such as network access testing, factory acceptance and on-site acceptance are not fully unified, resulting in defects in the standardization level of automation equipment. Develop a new intelligent redundant measurement and control device to provide power systems with excellent performance, advanced indicators, reliable and stable products, and dynamic migration is one of the keys to realize the redundant backup of interval measurement and control functions. The concept of dynamic migration is to realize that the cluster measurement and control devic...
