Embodiment Construction
[0035] The technical solutions and beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0036] This document-based remote operation method for setting values of relay protection devices involves a system in which the relay protection devices communicate with a setting value management client through a communication network. The fixed value management client exists as an independent software, or as a component of any system software, and is applicable to various application scenarios. As a component of the system software, it can be an application module embedded in the local monitoring system, guarantee master station system or dispatching system.
[0037] combine figure 2 The specific flow of the method is shown in the figure.
[0038] After the fixed value management client is connected to the relay protection device, it does not need to configure the fixed value model, and completes the fixed val...

The invention discloses a remote operation method for a constant value of a relay protection device. The constant value of the relay protection device flows in a system in a file manner; a constant value management client obtains a constant value model of the relay protection device through the file manner; a file is taken as an operation object in the operations of examining and modifying the constant value of the relay protection device; the constant value of the relay protection device is read through summoning an original constant-value file; the constant value of the relay protection device is modified through issuing a constant value updating file; and encryption transmission and error-proof check are added to the summoning link and the issuing link. According to the remote operation method, the mapping work of the constant value model in various communication links is simplified; the complexity of the system is lowered; the reliability of the system is improved; and the safety of the system is improved.
Description
technical field [0001] The invention relates to the technology of viewing and modifying the setting value of a relay protection device through a remote setting value management client through communication in the field of power systems, and in particular to a remote operation method for setting a value of a relay protection device. Background technique [0002] The fixed value is the basis for the correct action of the relay protection device. The correctness and adaptability of the fixed value play a very important role in the correct action of the relay protection and the safe operation of the power grid. With the widespread promotion of unattended substations and the improvement of automatic operation level, there is an increasing demand to view and modify the setting value of relay protection devices through the power dispatching data network and substation intra-station network from the remote setting management client. [0003] There are currently several application s...
