The direct current unlocking/locking time sequence simulation can simulate the unlocking and locking states of a specified direct current valve group (direct current pole). When a certain valve bank (direct current pole) of the analog direct current is unlocked, the communication testing device can automatically provide information such as an unlocking signal, a direct current control mode, set transmission power, maximum transmittable power, maximum liftable/regressive direct current capacity and the like of the valve bank (direct current pole) and send the information to a tested stable control system; when a certain valve bank (DC pole) of the analog DC is locked, the communication test device automatically sends a locking signal and a current DC control mode of the valve bank (DC pole), and clear 0 sending the transmission power, the maximum transmittable power, the maximum liftable/reducible DC capacity and the like of the locked valve bank (DC pole).

in the free time Tw, the transmission power of the fault pole is set to be 0, and other states are unchanged;
after the free time Tw is over, the transmission power of the fault pole is instantly restored to 90% of the power before the fault, and then is linearly restored to the power before the fault within 100 ms.
When Tf is larger than or equal to Tw, the communication testing device automatically simulates the line restarting process and the restarting failure final state:
in the free time Tw, the transmission power of the fault pole is set to be 0, and other states are unchanged;

The DC power ramp down timing simulation can simulate the power ramp down that occurs when a DC bipolar area fails or a minimum filter is not satisfied. The direct current speed reduction action parameter Ts can be set, and when the function is triggered, the time delay Ts sends data such as a direct current speed reduction signal, a direct current speed reduction identification bit and direct current speed reduction capacity to the stability control system according to a time sequence specified by an interface protocol standard.

The communication test apparatus further includes: the manual control time sequence simulation output test module comprises a state sequence time sequence simulation part and a manual setting part.
The state sequence time sequence simulation is used for sending state or power data to be modified to a stability control system according to a manually set sequence time sequence; state or power data that does not need to be modified remains unchanged;
the manual setting number can modify any content of the communication protocol by setting or setting number, and the test data sent after modification is changed immediately.
And data of a designated time period captured in the communication message can be received, the length of the data can be set to be 1s, and the data are stored in a memory of the special testing device according to the captured time sequence, so that the corresponding communication frame detection result and the communication stability detection result can be conveniently read and analyzed.
