Verb (abbreviation of verb) power dispatching guarantee scheme

(A) the main network operation mode arrangement

1. Yulin power grid is connected with Shaanxi main network through 750 Luo Heng I and II lines, 330 kV Henglong I line, Henglong II line, Hengtong line, Hengsui I line, Hengsui II line, Yuheng I line, Suizhu line and Tong Yan line.

2. The startup mode of Yulin Power Grid's provincial dispatching power plant follows the arrangement of provincial dispatching mode, and the small thermal power units, Daliuta Thermal Power Plant Units 3 and 4, Xinyuan 1 Unit 2, Donglai Power Plant 1 Unit 2 are connected to the grid, and Longxing Power Plant Unit 2 is disconnected.

3. Yulin power supply area: The open-loop point with Dabaodang power supply area is located at the side transformer switch of Hailiutan of 1 10kV Haishu I line. 1 10kV Chongqing-Kaifeng double-track line is transformed to the development zone, Zhuang Yan is transformed, and Zhuang Yan is transformed to supply power. 1 10kV Yuma double line supplies power to Majiamao substation. 1 10kV Yuhai Line supplies power to Hailiutan Substation. 1 10kV Yu 'nan, Yu 'yu and Yu 'hong lines supply power to Yulin rural power grid center.

4. In the network, except Baijiajian Substation, Boluo Substation, Huangfuchuan Substation and Zhaiyawan Substation, which belong to the company, are operated by a single main transformer, all other stations are operated by two main transformers. The operation mode of middle and low voltage side of main transformer follows the annual arrangement.

(II) Relevant precautions

1. During the Spring Festival, the power supply area of Yulin Substation will not be repaired except for emergency repair.

2. During the Spring Festival, if the second bus of development zone 10 kV is grounded, the 272 Yuzhong Line will eventually be pushed and pulled.

3, operating units at all levels and dedicated line users should be serious scheduling discipline, strict implementation of scheduling orders, enhance overall awareness, coordination, and jointly safeguard the safe and stable operation of the power grid.

4, serious scheduling discipline, smooth communication and reporting channels of power grid operation information. In case of accidents, obstacles and anomalies that affect the safe and stable operation of the power grid, the competent equipment unit shall report to the dispatching unit in time according to the relationship between equipment dispatching and management (the provincial direct dispatching equipment shall also report to the local dispatching center in time to make corresponding accident prediction).

5. Before the "Spring Festival", the operation and maintenance department conducted a special inspection on the equipment of the development zone 1 10 kV Chongqing-Kaifeng double-track line and the substation to deal with the defects in time to ensure the safe and stable operation of the power grid during the Spring Festival.

(three) the main network equipment failure accident treatment scheme

1, Yulin transformer main transformer fault

When the main transformer of Yulin Transformer N- 1 fails, if the main transformer is overloaded, the load can be transferred or controlled according to the provincial dispatching instruction.

When the main transformer N-2 of Yulin Transformer fails: 1), the Yulin power supply area is disconnected from the main network. If the low-frequency and low-voltage load shedding devices in the network operate, Shanghe Power Plant and small thermal power plants in rural power grid will maintain isolated network operation, and Yulin power supply area will not lose pressure. According to the provincial dispatching instruction, the frequency modulation of Shanghe Power Plant is coordinated by controlling the load in the network. If the two main transformers can't be restored in a short time, contact the provincial dispatching bureau to merge the Yulin power supply area into the Yulin North Network through 1 10kV Yuhai II line at the same time. (Note: Yuhai No.2 switch in Yulin Substation has no synchronization device, and the loop closing operation can only be carried out after the synchronization of Yulin North-South Network. The reclosing mode of related lines needs to be adjusted before the operation of Yuhai Ⅱ switch). Monitor the load of 1 10kV Jyukai-Yuhai II line to avoid overload of related equipment. After merging into Yulin North Network, the terminal sensitivity of 180 Company I line and 280 Company II line is not enough. Dispatching will focus on the closing inspection of Er Yulin Substation on Yuhai Line in the same period, with no pressure at Hailiutan side, Haishu line side and elm bay side. After any main transformer in Yulin Substation is restored, it is connected to the grid at the medium voltage side of the main transformer at the same time, and the operation mode is restored to the pre-fault mode, and the reclosing mode of Yuhai Ⅱ and Haishu lines is changed to the pre-fault mode.

2. In case of voltage loss in Yulin power supply area, Yulin Company directly supplies voltage loss to 1 10kV development zone substation, Zhuang Yan substation, Zhuang Yan traction substation, Majiamao compressor station and Hailiutan substation. Yulin Rural Power Grid 1 10kV Nanjiao, Xisha and other 17 substations lost voltage.

① Turn on Yulin Substation 1 10kV Yuxi, Yunan and Yushang switches, and turn on Yushu II switch 1, 2. Take10kV as the line between Shu-Jyukai I and Yuhai II, and take tidal flat, development zone, Zhuang Yan Substation and Yuhai II.

② Pay attention to the load of 1 10kV Dangshu-Jyukai I-Yuhai II line. If any line is overloaded, control Majiamao to change the load until the overload phenomenon disappears (Note: control the current of Dangshu line, Jyukai line and Yuhai line not to overload the line).

(3) If Shanghe Power Plant meets the grid-connected conditions, the dispatcher will adjust Yulin Substation of Yuhai II Line to check the same period, and there is no pressure on the beach side, Haishu Line, elm bay side, Shudang Line, elm bay and Dabao Substation, so Shanghe Power Plant can be connected to the grid.

(4) After any main transformer of Yulin Substation is restored, Yulin power supply area will resume its pre-fault operation mode. The reclosing mode of Yuhai Ⅱ, Haishu and Shudang lines was changed to pre-fault mode.

Note: When Yulin power supply area loses voltage, when the line provides security power to Yulin power supply area through 1 10kV Yuhaishu —— when the line provides security power, the protection of sections II and III of Haiyang line and sections II, III and IV of zero sequence current do not match the protection of Ma Yu 1, 2, 1 and 2 lines. When the quick-acting protection of the above 1 10kV line is withdrawn for some reason, the corresponding lines will be shut down at the same time.

3, development zone transformer main transformer fault:

When the main transformer N- 1 in the development zone fails, if it is a backup protection action, after checking that there is no abnormality in the voltage-loss buses and feeders, all outgoing feeders on all voltage-loss buses will be pulled away and forcibly sent to the main transformer. After the forced power transmission is successful, the power supply of each feeder will be restored one by one (priority will be given to restoring the power supply of important users such as government, schools and hospitals). If it is the main protection action, close the 100 bus coupler switch to restore the power supply of the lost voltage bus. Notify the operation and maintenance department to check the main transformer and carry out emergency repair.

When the N-2 transformer in the development zone fails and the low-voltage bus in the development zone loses voltage, notify Yuyang Branch to transfer the transferable load. According to the protection action of the faulty main transformer and the field equipment, a main transformer is selected for trial delivery. After the trial delivery is successful, the outgoing load will be gradually restored (priority will be given to restoring the 272 Chongqing Central Line). If the tripping circuit or protection action is not restored, power transmission will not be conducted for the time being, and then power transmission will be conducted after the cause of the fault is found out. If the two main transformers can't be forced to send power or the trial transmission is unsuccessful, notify the operation and maintenance department to check the main transformers and carry out emergency repair, and notify relevant users.

4. 1 10kV double-circuit fault trips at the same time:

Transformer in development zone, transformer in Zhuang Yan and traction transformer in Zhuang Yan are out of voltage, and Huayuan Company is informed to transfer the power consumption of the company and Yinhe Hotel to the standby line of Yulin rural power grid. According to the protection action and the inspection of the equipment in the station, after checking that there is no obvious abnormality in the relevant equipment, choose one of the two lines for forced power transmission. If the forced power transmission is successful, the main transformer and outgoing line operation of the development zone will be resumed as soon as possible (first, the power supply of Zhuang Yan traction transformer, government, hospitals, schools and other important users will be restored). And notify the relevant departments to repair the faulty line as soon as possible, and resume the normal operation of the development zone substation as soon as possible after the fault is eliminated.
