It is required that then recording operation time of origin, energy consumption and optimal value (the different start and stop in nearest 2 years of adjacent two operation rooms are counted
The data that operation is complete and energy consumption is optimal are found out in the start and stop record of state)；
4. the entire start and stop procedure parameter statistic of backstage programming count；
5. foreground shows the parameter trend of inquired start and stop various stages, support and design curve and all previous start and stop
Curve compares, and when selection is compared with design curve, parameter real value deviates standard value and touches institute to a certain degree
When the parameter alarm rule of setting, prompted in tendency chart top indicia red lines；
6. the parametric statistics result of foreground displaying start and stop process；
It is inquired 7. foreground according to the energy consumption and optimal value of adjacent two operation rooms of backstage statistics, calculates and shows
The energy consumption and optimal value in stage, energy consumption index include coal consumption, rate of water make-up and power consumption；
8. carrying out reason remarks on foreground when energy consumption actual value is than optimal value difference；
9. when the operating time of record is wrong, when can safeguard generation in foreground attended operation Rule of judgment or directly
Between, when attended operation Rule of judgment, benefit calculation task need to be established and recalculate operation time of origin；
10. safeguarding energy consumption statistic data on foreground, and store and arrive relational database when energy consumption statistic result is wrong.
Further, maintenance personnel safeguards that unit includes: to scheme in above-mentioned steps 1
1) maintenance personnel safeguards unit starting state Rule of judgment, the determination of unit starting state with high pressure when red switch outside
Cylinder lower flange temperature divides, and shares cold start, warm starting, four kinds of hot starting, hot start, very hot startup states；
2) maintenance personnel safeguards start and stop operations Rule of judgment and dead time；
3) when parameter is there are when standard curve, maintenance personnel safeguards parameter and standard curve and ginseng under different start and stop states
Number alarm rule is shut down standard curve and is determined by halt mode, including normal parameter shutdown, shutdown at sliding parameters, accidental shutdown；
4) when parameter needs to carry out data statistics, maintenance personnel safeguards statistical parameter and measurement type；
5) maintenance personnel safeguards energy consumption statistic index and superiority and inferiority direction, including is the bigger the better or the smaller the better.
Further, the dead time is operation duration to scheme, and unit min may be configured as 0.
Further, the operations Rule of judgment realizes that unit starting state is in pot by existing measuring point to scheme
Judged after furnace igniting operation.
Further, the benefit calculation task of establishing includes the feelings for service stopping or change operation judges condition to scheme
Condition is established and mends calculation task, can adopt number from real-time data base again, the calculating operation time, when it's the operating time pasts user maintenance, establishes
Calculation task is mended, the operating time of maintenance does not update.
Further, the parameter alarm rule can carry out regular configuration for absolute change or opposite variation to scheme.
Further, when online implementing, without the data of energy consumption optimal value, the later period is carried out scheme by the data of accumulation
It updates.
Further, in measurement process, measuring point leads to the record time anomaly that a certain operation occurs, user to scheme extremely
In the direct attended operation time of origin in foreground.
Further, after a certain operation occurs, the waiting time is more than that setting threshold value does not enter subsequent operation still to scheme, then
Terminate this start and stop record, and is identified as " open/shut down and is unsuccessful ".
The invention has the advantages that the present invention can be realized the parameter trend exhibition of start and stop various stages under different conditions
Show, compare and the statistics of the indexs such as energy consumption, provides guidance and analytic function for start and stop operation, help power plant management personnel complete
The operation that orientation understands operations staff is horizontal, and operations staff is helped to compare and analyze the start and stop process under same state,
The problem of finding out start and stop process improves the operation level and management level of Power Plant start and stop.
