Description
Technical field
The invention belongs to electric system high-voltage dc transmission electrical domains, and in particular to a kind of automatic function of direct current transportation monitoring system
The checking method and implementation procedure of rate curve monitor.
Background technique
Direct current transportation power control (powercontrolofDCtransmissonsystem) DC power transmission control system
One link.The power of direct current system transmission is maintained at given value by it.It is a kind of control function for belonging to pole control hierarchy.
In general, to the control of direct current transportation transmission power being realized by changing the current setting of DC current regulator.
According to the adjustment of grid operation mode and the variation of daily load, actual running DC transmission engineering is every
It is required under the arrangement of control centre, carries out the adjustment of transmission power, and the parameter of adjustment mainly needs at the specified time point
The performance number to be conveyed.
Power control usually has there are two types of operation control method: (1) it manually controls, power definite value and power ramp rate,
It is manually entered by operations staff.(2) it automatically controls, power definite value presses preparatory programmed direct current transmission power and changes (one automatically
As unit of day).When daily power adjustment point is more, due to being computer according to time point under automatic control mode
Power planning value is sent, therefore the workload of operations staff can be reduced.
The cardinal principle of the implementation method of automated power is saved in the server after power curve is adjusted, and is arrived at time point
Corresponding power instruction is sent after reaching, referring to " bipolar automatic power control method of high-voltage direct-current transmission " (application number:
201010245127.1), in automated power control in addition to needing power setting valve, it is also necessary to calculate power slope value and shift to an earlier date
Amount, referring to " a kind of HVDC transmission system in automatic power control method " (application number: 201110438628.6).
Automated power project documentation, the daily power transmission meter corresponding to a DC transmission engineering of control centre's publication
It draws, file format is Excel file, and content is temporally to put the power transmission plan of arrangement, general every 15 minutes power
Point, daily 96 power points.
In practical projects, after operations staff receives automated power curve, there are two types of mode is whole in automated power plan
Determine to be input in server on work station, the first is manually entered after printing, and second is imported by file, i.e., scheduling
The automated power file at center is importing directly into system for executing.After the completion of input, it is also necessary to carry out a series of meter
Calculation process, to guarantee to adjust the consistency of data and primitive scheduling centre data, after the completion of adjusting, it is also necessary to each click-through
Row verification of data, to guarantee the correctness of data.Since current load scheduling is increasingly accurate, the same day is likely to occur multiple curve tune
Whole situation requires to check after adjusting automated power curve again every time, needs to occupy a part of manpower and time, especially
If the time of adjustment is tighter, such as power planning issued in 30 minutes in advance is process 15 minutes of removal power lifting, practical
The time of reservation is only left 15 minutes, it is therefore desirable to complete the verification and inspection of data, by a kind of mathematical method to reduce
The workload of operations staff's verification.
In the operational process of automated power, operations staff is needed attentively to monitor implementation procedure, is examined with what is guaranteed and dispatch
Nuclear Data is consistent, needs to occupy a large amount of time and efforts of operations staff, if there is a kind of automatic method of monitoring implementation procedure,
Operations staff is reminded when deviation occur in actual power and scheduling examination data, then operations staff can be effectively relieved and supervise disk pressure
Power.It yet there are no report！
