
SMV and GOOSE analysis
Analyze the SMV and GOOSE.
1.4 Technical features
1) Available for different kinds of test in MU.
All can be tested: Electronic transformer and digital quantity input of MU,
Electronic transformer and simulation the consolidation of small signal input of
MU, Analog input the merger of the conventional transformer unit, mixed input of
MU.
2) High-precision of analog output
Six channels of current and vulgate are better than ±0.05% in output accuracy
outputting by the analog routine transformer.
12 channels of small-signal vulgate output are better than ±0.2% in output
accuracy outputting by the analog consolidated instrument.
3) Accuracy test (ratio error and phase displacement etc.), available for
synchronization and interpolation methods
In allusion to the service condition using MU in practice, receiving system will
use the synchronous data calculating mode for network port data and use
interpolation calculating mode for point to point data. To ensure the precision’s
absolutely accurate in networking mode and point to point mode of
MU,POM2-3333 can do the precision test in synchronous method and
interpolation method.
。
4) High-precision of message time synchronization
The appliance receives the digital message then time scale in high-precision
hardware according to FPGA, adds up the sample value packet’s sending
discrete degree accurately and computationally.
The precision of hardware timing is better than 40ns.
5) High-precision for MU delay test
Providing two mode of delay test for MU makes the precision much higher.
6) Simulate the clock tester
Can simulate the clock tester and test the punctuality error and the pair error
accurately.
7) Analysis digital messages in real-time
