In the middle of practical application, after detecting that working power breaks down, control the first branch switch and perform prepared auto restart action, control the second branch switch by the time relay performs prepared auto restart action after 3 seconds simultaneously.3 seconds upon a fault during this period of time in, whether the prepared auto restart action detecting the first branch switch runs succeeded, when not running succeeded, when upon a fault the 3rd second, prepared auto restart action is performed, to prevent the generation of power down accident by the second branch switch.
According to the embodiment of the present invention, provide a kind of embodiment of the method for the inlet wire prepared auto restart control method for transformer station, it should be noted that, can perform in the computer system of such as one group of computer executable instructions in the step shown in the flow chart of accompanying drawing, and, although show logical order in flow charts, in some cases, can be different from the step shown or described by order execution herein.
Fig. 3 is the flow chart of the inlet wire prepared auto restart control method for transformer station according to the embodiment of the present invention, and as shown in Figure 3, the method comprises the steps:
Step S21, when working power breaks down, controls the first switch and performs prepared auto restart action, and controls second switch perform prepared auto restart action after first scheduled time.
Step S23, very first time when breaking down according to working power and first scheduled time determine that the very first time interval.
Step S25, in very first time interval, Real-time Obtaining first switch performs the execution result of prepared auto restart action;
Step S27, when execution result is for running succeeded, cancels the prepared auto restart action of second switch after first scheduled time.
Concrete, realize controlling prepared auto restart action by step S21 to step S27.Wherein, by carrying out Real-Time Monitoring to the working condition of working power, determine whether working power breaks down.When working power breaks down, control the first switch and perform prepared auto restart action, and after first scheduled time that working power breaks down, perform prepared auto restart action by time relay control second switch, with the prepared auto restart failure preventing the first switch from causing due to fault.When controller detects that the first switch performs prepared auto restart action success, cancel second switch and perform prepared auto restart action.Thus achieve the object starting the action of low-pressure side prepared auto restart after the failure of high-pressure side prepared auto restart in time, achieve the technique effect preventing the transformer station's power down caused due to prepared auto restart baulk, solve in prior art because prepared auto restart is not activated the technical problem of the transformer station's power down caused.
