Description
Technical field
The present invention relates to the changing method of two cover intelligent terminal remote signalling amount in a kind of intelligent substation, belong to power system transformer substation technical field of automation.
Background technology
Along with being in full swing of intelligent substation construction and developing rapidly of intelligent substation technology, accelerate the paces that secondary device optimizes and combines, based on the basic demand optimized and combined secondary device and intelligent substation Protection Technology code requirement, the two cover intelligent terminal of single cover measure and control device access should be adopted for 220kV and above, the GOOSE network of intelligent terminal duplicate system retrofit all follows separate principle, when a Network Abnormal or the operation not affecting another network when exiting, first set intelligent terminal access A net, second cover intelligent terminal access B net.
Single cover measure and control device accesses separate A net and B net, corresponding reception duplicate system retrofit two overlaps the GOOSE remote signalling amount of intelligent terminal, owing to there is duplexed system, owing to there is no unified standard, therefore according to which kind of principle, how to determine that unique and effective remote signalling amount data source signal truly reflects the state of switchgear, avoid the state of two cover intelligent terminals to repeat to send or entanglement, become insoluble problem.
Summary of the invention
To the object of this invention is to provide in a kind of intelligent substation the changing method of two cover intelligent terminal remote signalling amount, to avoid the state of two cover intelligent terminals to repeat sending or the stability of a system that entanglement causes and the problem that reliability reduces.
The present invention to provide in a kind of intelligent substation the changing method of two cover intelligent terminal remote signalling amount for solving the problems of the technologies described above, and this changing method comprises the following steps:
1) intelligent terminal is left any distance in plug-in unit firmly open into be set to open into power monitoring open into;
2) make to open time of trembling that disappears that power monitoring opens be less than in critical field all the other firmly open into disappear the time of trembling;
3) according to receiving the state opened into power monitoring, two cover intelligent terminal is switched, when receiving any a set of intelligent terminal to open into power monitoring remote signalling amount state being 0, be switched to open into power monitoring state remote signalling amount be 1 that a set of intelligent terminal.
Describedly stop refreshing remote signalling quantity of state when receiving any a set of intelligent terminal to open into power monitoring remote signalling amount state being 0, retain that to open into power monitoring state be all GOOSE remote signalling amount states of last change before 0.
Described when be switched to, another set of to open into power monitoring remote signalling amount be the intelligent terminal of 1, as remote signalling amount data source and automatically Flushing status amount.
Described opening into power supply is that intelligent terminal leaves firmly into power supply, by GOOSE remote signalling amount gives measure and control device.
The described time of trembling that disappears is adjusted by configuration tool, and measure and control device receives to hold and firmly can hold into remote signalling amount state prior to all the other into power monitoring remote signalling amount state, makes measure and control device have sufficient time to judge to open the state into power monitoring.
The invention has the beneficial effects as follows: the present invention first intelligent terminal is left any distance in plug-in unit firmly open into be set to open into power monitoring open into, then by open time of trembling that disappears that power monitoring opens be less than in critical field all the other firmly open into disappear the time of trembling, measure and control device carries out the switching of two cover intelligent terminal according to receiving the state opened into power monitoring, when receiving any a set of intelligent terminal to open into power monitoring remote signalling amount state being 0, and stop refreshing remote signalling quantity of state, measure and control device can retain that to hold power monitoring state be before 0, all GOOSE remote signalling amount states of last change, can automatically switch to simultaneously hold into power monitoring state remote signalling amount be 1 that a set of intelligent terminal, thus realize the switching of two cover intelligent terminals.The present invention, when ensureing network communication reliability and intelligent terminal is stable, reaches two cover intelligent terminal remote signalling amount intelligence and switches.
Accompanying drawing explanation
Fig. 1 be the present invention for the network diagram of the two cover intelligent terminal of list cover measure and control device access;
Fig. 2 opens into power monitoring schematic diagram in intelligent terminal;
Fig. 3 is the waveform schematic diagram of the time of trembling of disappearing in the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
The present invention for intelligent substation in the two cover intelligent terminal network of single cover measure and control device access, as shown in Figure 1, measure and control device provides 2 independently 100,000,000 fiber optic Ethernet mouths, for the access of the two net general object of process layer intelligent terminal, process layer 2 overlaps intelligent terminal and accesses A cover network and B cover network respectively, completely independent on 2 cover network physicals, the GOOSE network of any a set of network is independent.Intelligent terminal and primary equipment adopt cable to be connected, and realize the state acquisition to primary equipment, often overlap intelligent terminal and all comprise complete switchgear state information.In this intelligent substation, the detailed process of the changing method of two cover intelligent terminal remote signalling amount is as follows:
1. intelligent terminal all run in plug-in unit design any distance firmly open into for open into power monitoring open into, as shown in Figure 2.
2. arrange open time of trembling that disappears that power monitoring opens firmly be less than within the scope of standard configuration all the other should open into disappear the time of trembling, and to be adjusted by intelligent terminal.Open firmly to open into supervision due to power supply and be less than all the other into the time of trembling that disappears and firmly open into disappearing the time of trembling, as shown in Figure 3, measure and control device can be preferentially received power supply and hold into monitored state.
3. measure and control device opens according to what receive the remote signalling amount switching automatically carrying out two cover intelligent terminal into power monitoring state, when receiving any a set of intelligent terminal to open into power monitoring remote signalling amount state being 0, stop refreshing remote signalling quantity of state, measure and control device retains that to open power monitoring state be before 0, all GOOSE remote signalling amount states of last change, automatically switch to simultaneously open into power monitoring state remote signalling amount be 1 that cover intelligent terminal, remote signalling amount state is overlapped for data source state with this, and start to refresh the remote signalling quantity of state of access corresponding to intelligent terminal in real time.
The present invention can make two cover intelligent terminals automatically switch each other, when there is mistake in any a set of intelligent terminal remote signalling quantity of state, switch to another set of, the state avoiding two cover intelligent terminals repeats to send or entanglement, thus determines that unique and effective signal truly reflects the state of switchgear.Add the reliability and stability of system, it will obtain applying more and more widely in high pressure level intelligent substation.
