, Ltd.
Preparatory Office Inter-duty Power Generation Competition Guidance Plan", stimulate the subjective initiative of power station production personnel and the labor enthusiasm of operators to grab power generation, and establish the awareness
of "power generation must compete and particles return to the warehouse".

3.
Report the previous day's electricity completion and various problems affecting power generation at the daily production morning meeting, and record the causes and impact of power generation values in detail for problems affecting power generation, and briefly analyze
.

4.
Contact and communicate with the dispatching center every day, timely understand the power grid information, report the production and operation of the power station to the grid dispatcher, obey the dispatching command, and obtain the support
of the dispatching personnel.

5.
Communicate with the dispatching and operation department, dispatching planning office and dispatching duty officer of the power grid company at least twice a month, and do work through multiple channels and aspects to ensure that the monthly utilization hours are not lower than the average utilization hours
of new energy of the power grid company.

6.
The value chief should focus on monitoring AGC, AVC, SVG, optical power prediction, two detailed rules, etc.
, and ensure that each network-related equipment operates normally according to the "Qinghai Datang International New Energy Co.
, Ltd.
Network-related Equipment Operation Management Measures", is not evaluated by the power grid, reduces the power limit ratio, establishes a good working relationship, and strives to strive for the power grid's incentive power plan
.

7.
The power station should regularly strengthen the cleaning of the panels every month, and strengthen the cleaning frequency in the season of strong wind and sand to keep the surface of the panels clean
.
Winter is the season of heavy snowfall, each power station should grasp the weather changes in recent times in advance, especially when the rain and snow weather continues, contact enough cleaning personnel in advance to prepare for cleaning, timely carry out the cleaning of the battery plate snow, to avoid the long-term snow of the battery panel affecting the power generation
.

8.
At the turning point of the change of the incidence angle of the sun at the spring equinox, summer solstice, autumn equinox and winter solstice, the adjustment of Golmud photovoltaic 9.
6MW adjustable bracket should be prepared in advance according to the adjustment month, and the adjustment should be completed in time to increase power generation
.

9.
The on-grid electricity price of the first phase of the Golmud photovoltaic project is 1.
15 yuan / kWh, and the on-grid price of the second phase is 1 yuan / kWh, actively communicate with the power grid, and limit the load of the second phase when the power grid is limited, and try to let the first phase expire
.

10.
Compare and analyze the two factory power supplies, consider from many aspects such as reliability and economic benefits, choose from the best between the two, give priority to the grid power supply when the power supply is stable and the unit is full, select the spontaneous power supply during the unstable power supply of the power grid and the load limitation of the unit, and reduce the purchase of electricity
.

11.
Strengthen the training of operation posts, improve the business skills and practical operation level of operation personnel, focus on improving the ability to deal with accidents, improve the overall quality of operation personnel, and ensure the healthy and economic operation
of the power station.

12.
Increase the intensity of defect management, reasonably arrange night elimination, the work that affects the load of the power station and the planned deficiency elimination is generally arranged after the withdrawal of the network, when the defect affecting the output of the power station occurs, the station manager must be present to coordinate, supervise the elimination, and the length of duty during the elimination period should contact the dispatcher in time to ensure that the total load of the whole power station remains unchanged
.

13.
For the elimination of defects affecting the load of the power station, the operating personnel should actively create conditions to cooperate with the elimination, improve the quality of work, do a good job in equipment maintenance measures and recovery measures after maintenance in the shortest possible time, and shorten the maintenance time
of equipment.
Grasp the progress of equipment maintenance in time, and prepare
in advance for the restoration of normal output of the power station.

14.
According to the operation status of each equipment of the power station, analyze the operation health status of the power station equipment, manage all equipment in stages, focus on monitoring the equipment with poor power generation, propose the best operation mode, and limit the inverter and other equipment
with low power generation efficiency during the load limitation period.

15.
Strengthen equipment inspection and analysis, according to the operation of equipment and inspection conditions, timely find equipment defects, for defects that may cause power outages and reduce output, the operation personnel should promptly notify the outsourced maintenance personnel, station manager and safety production department for rapid treatment
.

16.
Improve the coverage and correctness of standard votes, and further increase the pass rate
of two votes.

17.
According to small indicators, operators should grasp economic operation according to fine management, careful maintenance, accurate analysis, and accurate adjustment, praise the advanced, encourage the backward, and use the power generation competition between values to improve the enthusiasm of
the operating personnel.

18.
Formulate various publicity measures and control measures for saving electricity, implement the awareness of saving electricity, and turn off lights and computers and heating equipment in office and living areas in time; Organize the removal of line obstacles during power failure, wipe and maintain the line insulators, and reduce line leakage; Strengthen the regular cleaning of dry change, temperature measurement at the cable head, and explore the impact
of the change of cable head wiring method on power loss.
Energy saving, reducing power consumption and increasing power generation
.
