Protect whole group behavior and time test, automated system performance test, snowslide inspection and applied in network performance test.
9. the test method of the test system according to claim 8 for substation secondary device prefabricated cabin, feature
It is：The equipment information interaction test, including the start failure protection between verification protective relaying device, lock-reclosing lock, shunt tripping
The correctness of information exchange response；Verify the correctness of five anti-block signal interactions of monitoring system；
During the relay protection whole group behavior and time test, including the system failure, function is matched between verification protection equipment
The correctness of conjunction and the correctness of sequence of movement；Test sends out whole process since failure to relay protection trip signal
Time, as relay protection whole group actuation time；
The automated system performance test, including telemetering, remote signalling, distant control function verification of correctness, telemetering accuracy test, remote signalling
SOE time tests；System response time：Telemetering changes the time for being transferred to station level, and quantity of state variation is transferred to station level
Time, remote control execute the time；System loading rate index test：CPU normal duty rates, cpu load rate under accident, network are normally born
Lotus rate, accident lower network rate of load condensate；
The snowslide is examined, and in the case where setting fault mode, is carried out snowslide inspection, is obtained network load rate, cpu load rate, event
Journal situation, telemetering, remote signalling, remote regulating, remote control executive condition；
The applied in network performance test, including GOOSE message applied in network performance test, under given network load flow, test is protected
It protects tripping between measuring and controlling equipment and intelligent terminal, the correctness closed a floodgate and response time, and a certain in analog network secondary sets
It is standby to go wrong, in the case of mistake sends GOOSE message, the response condition and performance of other secondary devices in test network；
Sampled value applied in network performance test, under different background flow, whether test SV packet samplings value has packet loss or incorrect order, surveys
Try observing and controlling, function of measuring sampling precision；
Station level applied in network performance test, under heterogeneous networks flow, the communication between test protection measuring and controlling equipment and monitoring backstage
Performance, including the delay of MMS messages, the packet loss of protection or remote signalling event MMS, monitoring backstage transmitting order to lower levels, protection are surveyed
Control correctness and response time of the device to command response.
