Embodiment Construction

[0018] The present invention will be described in further detail below through specific examples.

[0019] A method for remote operation of the reclosing soft clamping plate, on-site implementation conditions: the substation is in the integrated self-mode, the bay layer is a bus or Ethernet structure, the substation of the relay protection information system is installed, and the self-injection and feeder protection devices are equipped with remote control soft clamping plates Implementation conditions: The substation has been connected to the RCS-9001 centralized control system, has two telecontrol networks, dedicated line channels (using DISA, 104 protocol), protection information system channels, and the centralized control center can perform remote control operations.

[0020] The control steps are:

[0021] Step 1. Use the soft press plate as a remote signaling point, and its status can be transmitted to the device as a time method, and remote switching can be realized di...

Abstract

The invention relates to a method for remotely operating a recloser soft pressing plate. The method comprises the following control steps: step 1, taking the soft pressing plate as a remote signaling point and transmitting the state to a device as a time manner; directly realizing remote switching by a remote control network and a digital channel, and judging and monitoring the state; step 2, modifying and configuring a remote transmission database; increasing remote control and remote signaling information quantity of a protection equipment soft pressing plate; step 3, carrying out a remote switching-off test on a spare power automatic switching function soft pressing plate; and step 4, quitting a debugged feeder line protection measuring and controlling device. A recloser is switched off through relay protection remote operation, and circuit electrified work is changed into a single circuit field working mode from original power transformation field and circuit field, so that the operation and management cost of a power grid is reduced; the labor intensity of operation and maintenance workers is alleviated, the power supply reliability is improved and the operation efficiency of the power grid is improved.

Description

technical field [0001] The invention belongs to the technical field of power grid dispatching, and specifically relates to a method for remotely operating a reclosing soft pressing plate. Background technique [0002] With the promotion and application of smart substations in the power grid, dispatching automation and substation automation are developing in the direction of digitization, integration, networking, standardization, marketization, and intelligence. With the rapid development of technology, the status of primary equipment is intelligent. , the improvement of stability, and the maturity of substation operation and other technologies are bound to have a profound impact on the existing substation automation technology. With the establishment of the IEC61850 standard communication protocol, the interoperability between devices from different manufacturers has been realized, and the degree of automation is getting higher and higher, which provides technical support fo...
