Embodiment Construction

[0051] Such as figure 1 As shown, a dynamic reconfiguration system for secondary equipment in a smart substation, the system includes: a management host and a general-purpose device that receives its control instructions.

[0052] The management host manages the general-purpose equipment, subscribes to the state variables of the general-purpose equipment, periodically triggers the self-check service of the general-purpose equipment, and monitors the running status of the general-purpose equipment.

[0053] The state variables include: power quality, ground point voltage, internal temperature of the chassis, CPU load, free memory, free external storage, number of running tasks, self-test results, restart times, running status, hardware model, operating system type and software version.

[0054] The general-purpose equipment is a backup secondary equipment and is deployed in the compartment layer.

[0055] The general-purpose equipment includes: a self-diagnosis module, a stat...

Abstract

The invention provides dynamic reconfiguration system and method of secondary equipment of intelligent substation. The system comprises a management host machine and universal equipment for receiving the control instruction of the management host machine. The method comprises the following steps of: (1) enabling the management host machine to obtain an SCD (Security Coding Device) model of the intelligent substation and analyze the CID model of the universal equipment; (2) monitoring the operation and stop of the universal equipment in an online manner, and displaying the equipment connection state; (3) subscribing for equipment state variable, calling self-checking service at regular time and estimating the operation state of the equipment in an online manner; and (4) when the equipment has a fault, controlling the restart or stop of the failed equipment as well as the operation of standby equipment. The dynamic reconfiguration system and method of the secondary equipment of intelligent substation not only can be used for sensing the operation state of the secondary equipment, but also meets the self-treating and self-healing requirement of the secondary equipment; overhauling can be completed immediately when the secondary equipment fails so as to recover the operation; and simultaneously, the universal equipment can be used for reducing the complexity of the system and improving the reliability of the system.

Description

technical field [0001] The invention belongs to the field of electric power automation, and in particular relates to a dynamic reconfiguration system and method for secondary equipment of an intelligent substation. Background technique [0002] In 2007, a local power supply bureau classified and counted the damaged secondary equipment of the substation. By consulting the operation records, ambient temperature during operation, weather conditions, and the exact time of equipment damage, the specific causes of the damage were found in groups, and the substations were analyzed. The classification of secondary equipment damage causes is shown in Table 1 below.
