Embodiment Construction

[0020] Such as figure 1 The centralized relay protection device shown includes a remote data collection unit, a remote action execution unit, a network switching unit, and a centralized control unit. The remote data collection unit collects information about the power system and sends it to A centralized control unit, the centralized control unit generates an action set, which is delivered by the network switching unit to the remote action execution unit. The centralized control unit is composed of a network interface unit, a data aggregation computing unit, a policy decision-making unit, a management unit, and an action data generation unit; the hardware and software foundation of the centralized control unit is to provide computing virtual virtualization, network virtualization, storage virtualization, and a high-performance cloud platform built on this basis.

[0021] The network interface unit interacts with the network switching unit to collect data and deliver action se...

Abstract

The invention discloses a centralized relay protection device. The centralized relay protection device comprises far-end data collecting units, far-end motion executing units, a network switch unit and a centralized control unit. The far-end data collecting units are used for collecting information of an electric power system and transmitting the information to the centralized control unit through the network switch unit, the centralized control unit generates a motion set, and the motion set is issued to the far-end motion executing units through the network switch unit. Control devices are deployed in a centralized mode, collecting and motion devices are deployed in a dispersed mode, and based on synthesizing positions of all the collecting and motion devices in electric power topology and historical operation data information of a whole net, the optimal motion behavior is done through decision making conveniently; an electric power topology network and a relay protective motion strategy can be configured on the centralized control devices flexibly, and the maintainability and the expandability of the system are improved.

Description

technical field [0001] The invention relates to the field of relay protection, in particular to a centralized relay protection device. Background technique [0002] Relay protection is an important measure to detect faults or abnormal conditions in the power system, thereby sending out alarm signals, or directly isolating and removing the faulty part; It is an automatic device that often monitors whether there are abnormalities or accidents in the interior, and can issue a trip command or signal; it is also an anti-accident automation measure that studies power system failures and abnormal conditions that endanger safe operation to explore countermeasures. It is called relay protection because relays with contacts were mainly used to protect power systems and their components during the development process. [0003] There are many kinds of relay protection devices in the power system and the deployment points are scattered. The action priority among various protection devic...
