The 'one-key sequential control' is that a large number of complicated manual switching operation steps are solidified on a special background computer, and as long as a required 'operation task' is clicked on the computer, the computer can automatically complete a series of equipment remote control operations, and meanwhile, whether the operation is in place can be automatically verified, so that the operation is ensured to be correct.
In the past, manually operating a 110 kv line to stop (send) power takes about 30 minutes, during which time the operator and the monitor were required to repeat the steps of starting, repeating, operating, checking on site, etc., which can be said to be time consuming and labor intensive. Nowadays, only one operation task needs to be clicked on the computer, the computer can remotely complete the remote control operation of all the equipment according to a set sequence within 5 minutes, and the operation process does not need the participation of workers. The application of one-key sequential control not only greatly improves the working efficiency, but also greatly reduces the power-on and power-off time, and makes an important contribution to the power supply reliability.
The one-key sequential control realizes the conversion of the switching operation of the transformer substation from manual one-by-one operation to computer remote automatic operation, is favorable for comprehensively improving the operation efficiency, reduces the operation risk and improves the emergency handling capability.
The one-key sequential control of the intelligent substation means that the sequential control function of the intelligent substation is utilized in the advanced application function of the intelligent substation, common operation of the substation is programmed into an operation module button on a monitoring background of the intelligent substation according to certain five-prevention logic, and an operator does not need to program an operation ticket with complicated content during operation and can complete the purpose operation only by calling the operation ticket corresponding to the one-key sequential control button according to the name of an operation task.
Compared with the operation of a conventional substation, the adoption of one-key sequential control has the following 4 advantages.
(1) One-key sequence control does not need operators to compile operation tickets on site, does not need drawing board simulation, does not need five-prevention inspection before operation of a conventional transformer substation (one-key sequence control adopts inspection in the operation process), and saves the preparation time of operation. The five-prevention inspection is as follows: the circuit breaker is prevented from being pulled and closed by mistake; prevent the false entering into the electrified interval; the isolating switch is prevented from being pulled and closed under the load; preventing the disconnecting switch with the grounding knife switch or the grounding wire from closing the isolating switch; prevent to hang the earth wire or close the earthing knife-switch with electricity.
(2) By adopting the modularized operation order, the completeness and the correctness of the content of the operation order can be ensured only by enhancing the examination of the operation order and the transmission test of the field actual operation when the one-key sequence control operation order is compiled, the influence on the safety and the correctness of the operation due to the different technical quality and the different recognition conditions of the operator on the equipment is avoided, and the misoperation possibly generated when the operator compiles the operation order on the field is avoided.
(3) The monitoring background is adopted for sequential control, the remote control operation and the state check of the operation order are automatically executed by the computer according to the program, the operation missing and missing items can not occur, the operation speed is high, the efficiency is high, the operation time is saved, the labor intensity of operators is reduced, and the automation level of the operation of the transformer substation is also improved.
(4) By adopting a 'button' operation mode, if one-key sequential control and an equipment state visualization system are tightly combined, the equipment state checking function is further perfected, the remote operation of a centralized control station or dispatching can be possible, the human resources are saved to a certain extent, and the problem of insufficient operators is solved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
