(2) The failure of the operating equipment can not affect the normal operation of the system.
In this embodiment, the setting value is determined by adding a current quality code to the determination logic.
In this embodiment, the interlock switching switch is logically set by the interlock starting device.
Example (b):
the slag removal DCS system of the power plant is added with the interlocking logic of the flushing water pumps, wherein the flushing water pumps of the unit A and the unit B are interlocked with each other, and the flushing water pumps of the unit C and the unit D are interlocked with each other.
When the current of the operating pump is lower than 100A (the judgment of the increased current quality code) and is delayed for 60 seconds or 5 seconds of pulse is generated after the fault of the operating water pump to start the standby water pump logic (an interlocking switch is arranged), once the fault of the operating water pump occurs, the normal operation of the deslagging system can not be influenced.
1. Increasing the current of the running pump to be lower than 100A by the pump A and the pump B, delaying for 60 seconds by judging the current quality code or jointly starting the standby water pump logic by pulse and interlocking on-off switch input signals 5 seconds after the running water pump fails;
2. and increasing the current of the running pump to be lower than 100A by the second unit C and the second unit D, delaying for 60 seconds by judging the current quality code, or performing pulse and interlock switching switch input signals for 5 seconds after the running water pump fails to start the standby water pump logic in a linkage manner.
3. The standby pump can be normally started in a low-current experiment;
4. the on-site accident button can stop the normal joint starting of the standby pump.
The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined by the appended claims and their equivalents.
