A substation bay layer device with self-recovery function and its realization method

Abstract

The invention relates to the field of power system automation, in particular to bay level equipment with a self-recovery function in a substation and an implementation method of the bay level equipment. The equipment comprises a monitoring self-inspection area, a function module and a slack resource module, wherein the function module and the slack resource module communicate with the monitoring self-inspection area, and the monitoring self-inspection area is controlled by adopting a CPU (central processing unit). According to the bay level equipment with the self-recovery function in the substation and the implementation method of the bay level equipment disclosed by the invention, on the basis of the development of a programmable logic device, by effectively utilizing hardware resources of the programmable logic device, application functions of the bay level equipment are divided; a monitoring operation and a switching operation are performed on running statuses of all the function modules by a peripheral monitoring module; when the bay level equipment breaks down, a fault module can be rapidly determined and isolated, and a self-recovery process is started, and therefore, the running safety and the running reliability of the bay level equipment are ensured, the workload of onsite repair and maintenance of the bay level equipment is relieved, and the running maintenance cost of the intelligent substation is saved.

Description

technical field [0001] The invention relates to the field of power system automation, in particular to manufacturing power system automation equipment and its implementation method, in particular to a substation bay layer equipment with self-recovery function and its implementation method. Background technique [0002] The intelligent substation bay layer equipment is mainly used to summarize the real-time data information of the interval process layer, implement the protection and control function of the primary equipment, and control functions such as the operation lock and operation synchronization of the interval, and has the communication function connecting the preceding and the following. At present, most of the bay layer equipment adopts a multi-processor system composed of CPU, digital signal processor (DSP) and field programmable gate array (FPGA), and sometimes even uses multiple multi-processor systems to realize the functions of a device . In this way of implem...

Problems solved by technology

In this way of implementation, on the one hand, a large number of hardware resources integrated by the multiprocessor system itself are idle because they do not meet the needs of device functions; Configured Performance Requirements

In addition, the larger the scale and the higher the degree of integration of a system composed of multiple multi-processors, the longer it takes to run and switch functions of the system, the more difficult it is to synchronize and share data, and the lower the resource utilization rate is. Advantages brought by the development of software and hardware resources

Most of the existing research objectives on the implementation of bay layer equipment focus on the data collection and arrangement of devices, the improvement of function integration, and the realization of some advanced applications, and less attention is paid to the self-adaptability and self-healing capabilities of bay layer equipment.
