Basic Requirements for Dynamic Test System

3.1 Simulation system performance requirements

3.1.1

In the simulated transmission capacity, the current value of the test product is close to the current value of the prototype system, and the difference

Not more than 10%. The secondary rated AC voltage of the analog system to the test product should be the same as that of the prototype system.

3.1.2

The secondary current value of the high voltage side busbar short circuit of the power plant shall not exceed 20% before the prototyping.

3.1.3

The short-circuit current secondary value through the analog line should correspond to the value calculated from the actual parameters of the analog system.

3.1.4

If there is no special requirement, the maximum short circuit current value of the simulation system can be considered according to the maximum short circuit capacity of the prototype system.

3.1.5

connected to the parallel reactor analog line, in the case of full voltage, the power side of the circuit breaker is disconnected, the residual voltage on the line

The transient low frequency component, the voltage decay to zero time is not less than 1s.

3.1.6
