Embodiment 1

[0051] see Figure 1-2 , This embodiment discloses a method for clamping the relay outlet of an intelligent substation, namely the binding method, which belongs to an artificially formulated modeling method. It is very convenient to solve the problem of being clamped, but it is not flexible enough. In this embodiment, AccessPoint is established for two processing boards respectively. 1# processing board corresponds to "G1 access point", which only includes the input virtual terminals with subscript [0], 2# processing board corresponds to "G2 access point", and only contains the input virtual terminals with subscript [1]; respectively establish ConnectedAP connections point. "G1 connection point" only includes 1# processing board network port, "G2 connection point" only includes 2# processing board network port. ( 5-A Among them, 5 represents the slot position of the corresponding processing board on the device, A is the first network port of the board, B is the second netw...

Embodiment 2

[0057] Based on the first embodiment, this embodiment discloses a method for clamping the relay outlet of a smart substation, that is, the unbinding method. This method does not need to manually formulate a modeling method, and the program processing method does not depend on the modeling method, which can be very convenient. Solving the pinned problem improves adaptability and flexibility, but is relatively complex. The unbinding method can be modeled separately according to the processing board as in the first embodiment, or can be modeled according to the whole device.

[0058] The unified modeling of the whole device is as follows: Establish a unified AccessPoint access point. All GOOSE input virtual terminals are built in "G1 access point", and are no longer distinguished by processing boards. Establish a unified ConnectedAP connection point. The network ports of the entire device are built at the "G1 connection point", and are no longer distinguished by processing boar...

Embodiment 3

[0082] An intelligent substation relay outlet clamping solution system, which can realize the intelligent substation relay outlet clamping solution method described in Embodiment 1 or 2, including:

[0083] Power-on initialization module: used to power-on and initialize the device prepared before operation;

[0084] Monitoring module: used to monitor whether the communication of each processing board is normal before responding to the control order of each processing board;

[0085] Control order clearing module: In response to any communication interruption of any processing board, all control orders of the processing board whose communication has been interrupted are cleared to zero before an export order is generated;

[0086] Control order obtaining module: used to obtain the control order issued by the processing board with normal communication in response to the normal communication of any processing board;

[0087] Password synthesis module: used to OR the cleared and ...

Abstract

The invention discloses an intelligent substation relay outlet clamping solving system and method in the technical field of intelligent substations. The method comprises the steps that a device which is prepared before operation is powered on and initialized; before responding to the control command of each processing board, monitoring whether each processing board is in normal communication; when any processing board is subjected to communication interruption, the control commands of the processing board with the communication interruption are all reset before the exit command is generated; in response to normal communication of any processing board, taking a control command issued by the processing board with normal communication; performing phase OR on the reset control commands and the taken control commands to generate outlet commands corresponding to outlets of the relays; and on-off of an outlet channel corresponding to the output plate is controlled based on the outlet order. According to the device, the fault influence range is reduced, and the problem that when only one processing board is abnormal, the other processing board of the device cannot be used for controlling an outlet channel of the output board, and then the function of the whole device is lost is solved.

Description

technical field [0001] The invention relates to a solution system and method for output clamping of a relay in an intelligent substation, and belongs to the technical field of intelligent substations. Background technique [0002] Smart substation is a reliable, economical, integrated, low-carbon, and environmentally friendly equipment and design. It is based on the digitization of all station information, the networking of communication platforms, the standardization of information sharing, the integration of system functions, the compact structure design, and the intelligentization of high-voltage equipment. It is a substation that can support real-time online analysis and control decision-making of the power grid, thereby improving the reliability and economy of the entire power grid. It can automatically complete basic functions such as information collection, measurement, control, protection, metering and detection. At the same time, it has advanced functions such as re...
