A relay protection setting value visualization method

Technical field

The invention relates to a fixed value setting of an alternating current transmission and a direct current transmission and a relay protection device, covering the fields of low voltage, medium voltage, high voltage, ultra high voltage and ultra high voltage alternating current transmission, and high voltage and ultra high voltage direct current transmission.

Background technique

AC transmission and direct current transmission require relay protection devices to identify and protect transmission equipment failures and transmission system failures. At present, relay protection devices are protected by microcomputers. The relay protection device needs to complete a series of algorithms for judging the failure of the transmission equipment and the failure of the transmission system; these algorithms all involve a series of set values, called relay protection settings.

The conventional relay protection setting has the following characteristics:

1. Inherent attributes: for example, name, dimension, maximum value, minimum value, minimum step size, setting value, etc.

2. Operationality: The microcomputer protection algorithm program can run the set value using the fixed value.

3. Tunability: The running relay protection device can change the set value of the fixed value and put it into operation without software update.

4. Readability: readable on the display screen of the relay protection device itself; readable on the workstation in the substation.

5, long-distance readability (remote): readable at workstations such as dispatch centers outside the substation.

6. Modify the operability: sub-device level, local level and telecontrol level; modify the operation on the interface configured by the device itself, on the workstation in the substation and on the workstation in the dispatch center outside the substation.

7. Multiple sets of suits: Multiple sets of fixed values are pre-existing in relay protection devices to adapt to different operating modes and operating conditions. Among them, only one set value is in the running (active) state; the remaining set values are in the standby state. A set of settings changes from the standby state to the running state, or a set of values changes from the running state to the standby state. This process is called setting group switching. The setting group switching can be performed manually or automatically according to the conditions.

At present, IEC 870-5-103 and IEC 61850 are widely used in China to protect communication protocols. Dynamic communication and telecontrol operation, including telecontrol communication and telecontrol operation of relay protection settings.
