What is the work content of substation?

Substation, where the voltage changes. In order to transmit the electric energy of power plant to a long distance, it is necessary to change the voltage into high-voltage electricity, and then reduce the voltage near the users as needed. The work of raising and lowering the voltage depends on the substation. The main equipment of substation is switch and transformer. Depending on the size, the small one is called a substation. Substation is bigger than substation. Substation: generally, it is a step-down substation with a voltage level below 1 10KV; Substation: including "step-up and step-down" substations with various voltage levels. The main work contents of the substation are as follows:

1. Preparation before handover: the shift supervisor should check the operation since this value, whether the operation of primary and secondary equipment in each station is in line with the actual situation, check and sort out the "two tickets", check and sort out various records, and check and sort out tools and meters; The supervisor shall report the daily electricity consumption by fax; The duty officer and the deputy duty officer shall assist the cleaners in cleaning.

2. Preparation before the succession: The successor shall wear the post sign and divide the work before the succession, and the monitor shall enter the substation duty room to check all relevant records and understand the operation status of the equipment.

3. Explain the operation: the shift supervisor shall explain the primary and secondary operation of the substation within the range of this value to the successor; Handling of operation, abnormality and accident, discovery and elimination of equipment defects; Maintenance, testing and other work; Security measures; Information about tools and instruments; The use of record books; Superior instructions, orders, etc.

4. On-site inspection: the successor shall inspect the secondary equipment, tools and instruments in the main control room according to the division of labor; 220KV system and 380V system and safety equipment; 1 10KV system; Check the 10KV system, report to the monitor after the inspection, and handle the handover formalities after it is confirmed.

5. Handling handover procedures: After the successor has checked that there is no problem, both parties will sign the duty book to record the handover time, and the shift supervisor will announce the successor to get off work.

6. Daily work: after the succession, make inspection records in the duty book, and the shift supervisor will check the clock, check whether the communication is smooth, check the scheduling record and enter the time of the day. Arrange daily work according to the station work plan and fixed work plan.

7. Switching operation: the shift supervisor (or shift supervisor) receives the scheduling command and records it, explains the operation task to the operators, and listens to the recording of the scheduling command. At the same time, the screen commander shall record the command, and the operator shall fill in the operation ticket and submit it to the guardian for review. After the long-term value is reviewed, the operation shall be carried out. After the operation, the guardian shall report to the shift supervisor, who shall report the execution of the order.

8. Accident handling: When an accident occurs, the attendant should check and reset the signal according to the dispatching command, observe the instrument change, check the light signal and the card drop signal, and make records. The officer on duty and the deputy officer on duty shall inspect the equipment, extract the fault wave recording information at the same time, analyze the accident according to the signal and the equipment inspection results, report the accident to the dispatcher in detail (report to the relevant superior leaders if necessary), and handle the accident and the accident handling process according to the dispatching order.

9. Maintenance cooperation: During maintenance, the work permit holder (on duty) fills in the work permit holder section, and other personnel on duty arrange on-site safety measures. After the safety measures are implemented, the licensor and the person in charge of the work should go to the site to explain the safety measures and the permitted work. During work, the personnel on duty and the deputy personnel on duty constantly check the safety work performed by the staff; After the work, organize acceptance, urge the maintenance personnel to clean up the work site, make maintenance records and defect records, go through the formalities for the end of the work, and report to the dispatcher after the formalities for the end of the work.

10. Work summary: After the work on duty, the shift supervisor will organize the whole class to make a work summary, sum up experience, learn lessons and propose improvement measures from the aspects of daily work, execution procedures, implementation of "two votes", accident handling and maintenance cooperation.
