Start test simultaneously, the feeder automation terminal equipment operating mode of tape test still enjoys control priority, at this time
If physical fault occurs for scene, i.e., after transformer substation side wire-outgoing breaker protective device detected, circuit breaker trip, institute's band branch
The terminal installation of way switch will detect decompression, and test pattern is immediately switched to operating mode, not influence to switch actual act.
The terminal installation of the tape test function includes operating mode and test pattern.
The emulation testing of analogue system 1 in the embodiment of the present application is the emulation testing carried out without terminal installation, and is surveyed
The test of test system 2 controls analog switch by terminal installation, is the test that tape terminal device carries out.
After the remote terminal unit networking success of test macro 2 and tape test function, the selection test pair in test pictures
As, and control mode switch operation is carried out for single feeder automation terminal equipment, terminal is switched into survey by operating mode
After die trial formula, terminal installation will simulate control object and switch to analog machine by actual switch equipment.Under test pattern, it is at this time
The switch state of system acquisition is analog machine state, and the voltage and current of acquisition is the feeder-terminal-unit test module journey that do not have a power failure
Sequence is preset.
Remote terminal unit with test function include device noumenon, logic judgment module, measurement preset module, open into
Output module and analog machine module；
Preset module is measured, for simulating decompression, having the electrical quantity signal of pressure, overcurrent, and is sent to logic judgment module；
Logic judgment module, the electrical quantity signal for being sent according to measurement threshold module, determines latch status；Root
According to the latch status, enabling signal is sent to input and output module；
The input and output module, the enabling signal for being sent according to the logic judgment module control analog machine
Module；The action message that analog machine module is sent is received, and is sent to evaluation system 3.
The present invention can plant in feeder automation main station system, is independently of feeder automation main station system, passes through people
The operation of each subsystem in test macro is completed at machine interface, meets electric grid secondary security protection related request.
User enters man-machine interface, selects communication access test macro mode, the remote terminal unit with function to be tested
Networking success.If tested into in-circuit emulation, control object is selected, configuration parameter is set.According to logical data base in system
Simulation executes test process, finally completes emulation testing.
If the remote terminal unit with test function is switched to test pattern into actual test.Analog switch control,
Action state Real-time Feedback, is sent to evaluation system, evaluates actual test result, forms test result, and evaluation terminates.
The test macro and method provided through the embodiment of the present invention can remotely realize feeder line when switching electrification
The dependence test of automation ensures reliably coming into operation for feeder automation, and then reduces amount when user malfunction has a power failure.
A kind of remote feeder automatization test system of the invention, test implementation step are as follows:
According to feeder automation on-site actual situations, communication access test macro mode is selected.Test macro, which can access, matches
The ready-made communication network of automation is communicated with terminal installation to be tested, can also pass through the 4G wireless receiving card on terminal installation
Constructing communication network is carried out, to assign instruction to terminal installation, and emulation mode feedback is received by terminal.When test, pass through band
The terminal installation simulation actual switch movement of test function, send test macro on switch motion state is real-time, and form time note
Record.After switch motion state feeds back to test macro, switching logic cooperation and time cooperation are checked in test macro, whether full is seen
Identification on the spot, isolation and the non-faulting region of sufficient line fault restore electricity.
After the feeder automation remote terminal unit networking success of test macro and the tape test function of control feeder switch,
Actual test object may be selected and carry out emulation testing, logically database i.e. set pattern then carries out for emulation testing, surveys to carrying out
The result of the action and action policy when examination form reference；
Before confirmation starts test, test macro is by the feeder automation remote terminal unit of tape test function by operating mode
It is switched to test pattern；
Simulated failure point, starts to test, and the remote terminal unit with test function will automatically record analog machine
Action situation and time interval form SOE record；
Test terminates, and test macro can analyze and determine action logic and process, thus exact p-value conclusion.
