Ethernet interface is connected respectively PWF master control board with optical fiber interface, for the data communication between PC control software and tester and tester and protective device.Wherein optical fiber interface comprises FiberA, FiberB and FiberC and CH1, CH2 and CH3, FiberA and FiberB are for sending the sampled value that meets IEC61850-9-1, IEC61850-9-2 agreement, FiberC is for subscription/publication GOOSE information, and CH1, CH2 and CH3 are for sending the sampled value that meets FT3 form.
PWF master control board comprises 32 embedded-type ARM (Advanced RISC Machines) processor and digital signal processor (DSP), for realizing ethernet communication and efficient data processing fast.
The automatic closed loop test system that comprises above-mentioned digital protecting tester; also comprise: computing machine, network access device; as hub(hub); the Ethernet interface of described digital protecting tester connects computing machine by network access device; described network access device is connected respectively protective device to be measured with digital protecting tester; for obtaining the information of protective device, computing machine is processed described information.The FiberA of this digital protecting tester, FiberB, CH1, CH2 or CH3 connect the SMV interface of described protective device for sending sampled value; FiberC connects the GOOSE interface of described protective device for subscription/publication GOOSE information; network access device connects the Ethernet interface of protective device; for the protection definite value of protective device described in read/write, read the sampled value of described protective device, tripping operation/combined floodgates report of reading described protective device, described definite value, sampled value, the report of tripping operation/combined floodgate are processed by computing machine.
Automated closed-loop method of testing based on said system, the method comprising the steps of: tester sets up test assignment according to test plan, automatically configures GOOSE parameter, automatically read/write protection definite value; Then according to test assignment and protection definite value simulated failure, automatically resolve GOOSE data acquisition test result, the fetch protection device tripping operation automatically/report of closing a floodgate, test finishes software and automatically generates a complete test report.
In the inventive method step, automatically configure GOOSE parameter.During tester subscription/publication GOOSE, must configure some basic parameters, these parameters must be in full accord with the configuration of protective device.The GOOSE information that must know tested protective device issue while subscribing to GOOSE, these information comprise some basic configuration parameters (destination address, GoCBRef and GoID etc.) of GOOSE and the definition of each data of data centralization; During issue GOOSE, must know the GOOSE information that tested protective device is subscribed to, these information comprise some basic parameters (destination address, GoCBRef, GoID and Dataset reference etc.) of GOOSE and the structure (comprising data amount check, data type) of GOOSE data set.Method of the present invention proposes following three kinds of modes and automatically configures GOOSE parameter:
(1) read GOOSE model file and obtain GOOSE parameter and DSD
CID or ICD file that the method is resolved protective device obtain its GOOSE issue, subscription information; this information comprises the descriptor of some basic parameters (destination address, GoCBRef, GoID and APPID etc.), GOOSE data set and each data thereof of GOOSE; wherein the basic parameter of GOOSE (such as MAC Address, GOID etc.) can configure automatically; tester only need to carry out according to opening of the description of certain GOOSE data and tester associated into (or outputing), open the value that directly reflects the GOOSE data that it is associated into the state of (outputing) in the future.Issue is during GOOSE, and the data set organization software of GOOSE generates automatically, and tester only need to revise certain or some GOOSE data values.
(2) test macro and protective device communication, read its GOOSE model and obtain GOOSE issue, subscription information
If there is no the model file of tested protective device; test macro can with protective device communication; read its GOOSE model; automatically obtain its GOOSE issue, subscription information, this information comprises the descriptor of some basic parameters (destination address, GoCBRef, GoID and APPID etc.), GOOSE data set and each data thereof of GOOSE.
Adopt in this way and to the requirement of protective device be: in protective device data model, must have GOOSE model or have independent GOOSE interface can read GOOSE model.
(3) resolve the GOOSE message of protective device issue, obtain its GOOSE and release news
The method is resolved the GOOSE message of protection issue automatically; obtaining its GOOSE releases news; this information comprises some basic parameters (destination address, GoCBRef, GoID and APPID etc.) and the GOOSE data set of GOOSE; but the descriptor of each data of GOOSE data centralization cannot obtain in this way, the device producer that needs protection provides.Can only subscribe in this way the GOOSE data of protection issue, can not issue GOOSE data to protective device.
In the inventive method step, the definite value of automatic read/write protective device.Automatically fetch protection definite value is the important process in the whole exploitation of test automatically.Test macro, as client, carries out communication with C/S mode and protective device, fetch protection definite value.
In the data model of protective device, setting valve and relevant action message thereof are to be modeled in each relevant logic node.As what define inside LLN0, be public definite value, PTOC node is regularly overcurrent protection contact.Definite value under its logic node of each producer is all placed on data centralization at present.The order of the order of data centralization definite value and fixed value list table is the same.According to the feature of protective device storage definite value; and the interaction times that reduces client and server; directly from data centralization, obtain definite value; obtain variable name, numerical value, description; pass to test macro; test macro does not need manual intervention (or the least possible) to parse definite value according to variable name, for simulated failure.In automatic testing process, user need to revise protection definite value sometimes, such as throw move back pressing plate, its method is as follows: first read SGCB(definite value controll block) obtain the value of definite value operational area, editing area, then editing area is revised as to operational area.Now all definite values of editing area are identical with all definite values of operational area, at editing area, revise definite value, finally confirm editor.After adopting in this way, tester only need to revise definite value, confirms editor.
In the inventive method step, automatically read sampled value.The sampled value of protective device (effective value of voltage, electric current, phase place) passes to backstage with the form of data set; generally can there be a fixing data set name in each protective device producer; reading out data collection can obtain the value of each variable; by the path of each element under data set, read in addition description, the unit of each data, thereby test macro can obtain title, numerical value and the unit of each sampled value.
In the inventive method step, the fetch protection device tripping operation automatically/report of closing a floodgate.Realization comprises that two parts one are to read report, and another part is the processing of reading after report.After main thread calls and reads report thread, this thread moves always, waits for the arrival of protective device action event, comes one to read one, and event is deposited in to buffer zone.Main thread reads the report of buffer zone before doing next test point, and empties buffer zone, take and guarantees the report that the content of buffer zone is next test point.
Above embodiment is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
