Abstract
The invention relates to a comprehensive automatic telemetry information tester of a substation, and solves the problem that some test items of a comprehensive substation automation system are difficult to test effectively at present. The comprehensive automatic telemetry information tester is characterized by comprising a switching value I/O (input/output) interface, an electronic relay module, a programmable logic array module, a CPU (central processing unit) module, a system time tick module, a power source module, a communication module and the like. An external telemetry information signal is received by the switching value I/O interface, isolated via the electronic relay module, subjected to logic reorganization via the programmable logic array module, input to the CPU module and compared with input quantity of the system time tick module and the communication module, the CPU module converts analog quantity into digital quantity and processes the same, and then the external telemetry information signal is output by the communication module. The comprehensive automatic telemetry information tester of the substation can solve the problem that comprehensive automatic telemetry information in the substation cannot be effectively tested, and guarantees accuracy and reliability of telemetry information operation information of a dispatching automation system.

Technical field
The present invention relates to a kind of telemetry intelligence (TELINT) proving installation, be specially adapted to transformer station's telemetry intelligence (TELINT) test.
Background technology
Along with developing rapidly of electric system; the complex automatic system of transformer station and generating plant comes into operation in a large number; the routine inspection need of work of this type systematic disposes all multiple instruments; for example: the calibration power source; the reaying protection test instrument; the AC sampling calibrating installation; the gps satellite tester; millisecond meter etc.; even but joined enough these instruments; some test event and index still are difficult to (for example: the full-automatic testing of remote signalling effectively test; SOE resolution test etc.); can only be undertaken by traditional manual or semi-automatic mode; inefficiency; because the impact of human factor; the confidence level of test result is not high; repeatability is bad, and causes the serious testing tool wasting of resources.
Summary of the invention
Purpose of the present invention provides a kind of automation of transformation substations remote signalling comprehensive tester exactly for low cost addresses the above problem.
Technical scheme of the present invention is a kind of automation of transformation substations remote signalling comprehensive tester, it is characterized in that: by switching value I/O interface, electronic relay module, programmable logic array module, CPU processing module, system to the time module, power module, communication module etc. form; Receive outside remote signals by switching value I/O interface, by the electronic relay module signal is isolated, the process programmable logic array module is with logic reorganization, then input the CPU processing module, Compare System to the time module and communication module input quantity, the CPU processing module converts analog quantity to digital quantity and processes, and is exported by communication module at last.Described communication module is that the RS232 interface is used for and the PC connecting communication, can control the remote signalling control enclosure by PC; Described CPU acquisition module is used for the exchange of data to be processed; Described system to the time module can be divided into three kinds: manual mode, the IRIG-B code to the time pattern, the gps clock pattern; Described programmable logic array module is the isolation signals that electronic relay was processed, and links to each other with CPU by logical combination, controls concrete remote signalling way output; Described electronic relay module is with the signal isolation of input, by dividing potential drop, filtering, offers the needed voltage of programmable logic array module; Described power module provides working power.
The present invention can solve at present can not effectively detect integrated automation of transformation stations remote signalling problem, guarantees accuracy, the reliability of dispatch automated system remote signalling action message; Reduce a large amount of execute-in-places.

Embodiment
With reference to accompanying drawing 1,2, the present invention receives outside remote signals by switching value I/O interface, by the electronic relay module signal is isolated, and with logic reorganization, then inputs the CPU processing module through programmable logic array module; The host computer software operation can make the automation of transformation substations remote signalling amount of leaving export simultaneously a certain road or a few road by the RS232 interface, and pulse width, recurrence interval, startup interval, the pulse number on a few roads also can be set; Compare System to the time module and communication module input quantity, the CPU processing module converts analog quantity to digital quantity and processes, at last by communication module with signal feedback to host computer.
[0008] remote signalling quantity of state input test: the amount of the leaving terminal correspondence of instrument is linked on the terminal of the measurement and control unit that will test, and from on-the-spot cut-off stream voltage access instrument, the DC voltage that applies should trigger the remote signalling switch motion.A deciliter test is carried out on available a few roads simultaneously in the operation, selects the required test number (TN) that carries out and maximum latency to test Loss Rate and the qualification rate of remote signalling.
Resolution test between different remote signalling: the amount of the leaving terminal correspondence of instrument is linked on the terminal of the measurement and control unit that will test, and from on-the-spot cut-off stream voltage access instrument, the DC voltage that applies should trigger the remote signalling switch motion.Arrange in the operation test the remote signalling number, start and interval time, pulse width, maximum latency to test the resolution between several remote signalling.
Two survey resolution test between action: the amount of the leaving terminal correspondence of instrument is linked on the terminal of the measurement and control unit that will test, and from on-the-spot cut-off stream voltage access instrument, the DC voltage that applies should trigger the remote signalling switch motion.Arrange in the operation test remote signalling number, action interval time, start the resolution between twice action testing interval time, maximum latency certain road remote signalling.
Snowslide test: the amount of the leaving terminal correspondence of instrument is linked on the terminal of the measurement and control unit that will test, and from on-the-spot cut-off stream voltage access instrument, the DC voltage that applies should trigger the remote signalling switch motion.The reaction time that the remote signalling group is inferior, maximum latency is come proving installation of test is set in the operation simultaneously.
In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation form, all drop on the protection domain of requirement of the present invention.
