Embodiment 1
[0026] An embodiment of the present invention, its process is as shown in the figure. in particular, figure 1 In step 1, it is described that it is judged whether a commutation failure occurs in the DC transmission system. If it occurs, the DC control and protection system sends the relevant commutation failure signal to the safety and stability control device, and the commutation failure time in the safety and stability control device is accumulated The timer starts timing and accumulates commutation failure time.
[0027] The main cause of system instability caused by continuous commutation failures is that the continuous sudden drop of DC transmission power makes the cumulative acceleration area larger than the deceleration area, and the cumulative acceleration area is positively correlated with the cumulative duration of commutation failures (see figure 2 ), the cumulative amount of commutation failure time (called the cumulative commutation failure time) is used as the ...
