Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention more comprehensible, with reference to the accompanying drawings and embodiments, to this
Invention is described in further detail.It should be appreciated that the specific embodiments described herein are only used to explain the present invention,
And the scope of protection of the present invention is not limited.
Below for promoting the power of two customary DC units, to illustrate problem of the existing technology.Institute as above
It states, under coodination modes, after direct current station monitoring and control equipment issues value and power reference and ramp rate, two customary DC units can be divided equally
Value and power reference and ramp rate.However, being arrived afterwards when two customary DC unit emergent powers successively reach power target value
Up to power target value customary DC unit during power rise climbing speed will become the half of ramp rate, after causing
Half section of power rise rate becomes smaller, and deviates schedule power curve, this is illustrated below.
As Figure 1-1, under coodination modes, value and power reference 2000MW, power ramp rate (refers to power in this example
Climbing speed) it is set as 200MW/min.Customary DC unit one first unlocks, its power rise rate is 200MW/min at this time.
When one power of customary DC unit rises to 500MW, customary DC unit two is unlocked.Subsequent customary DC unit one and customary DC
Two power rise rate of unit all becomes 100MW/min.But after customary DC unit one reaches 1000MW, customary DC list
First two power rise rates are still 100MW/min, fail the 200MW/min for reverting to setting, which will cause schedule power
Curve implementation deviation.
Discovery is researched and analysed, only when two customary DC unit emergent powers are inconsistent, and goes up and down power simultaneously
It will appear the case where power does not reach power target value simultaneously.But according to live actual condition, customary DC unit completes unlock
Afterwards, can't hoisting power immediately, and need to wait two customary DC cell powers balances that (two customary DC units are divided equally
After power) after hoisting power again.
Power balancing procedure is shown in Fig. 1-2 and Fig. 1-3.One customary DC unit (customary DC unit one) steady-state operation,
The unlock of another customary DC unit (customary DC unit two), customary DC unit two unlock moment meeting step and go out 100MW's
Minimum power.In order to eliminate this 100MW overshoot as early as possible, the power of customary DC unit one is reduced with the rate of 300MW/min
20s reduces 100MW, such as the 1. process in Fig. 1-2.This latter two customary DC unit is started with the active coordination rate being arranged
Power is balanced until two cell powers are equal (t3 moment).
It is found according to field operation experiences, above procedure has problems in that t2~t3 process 2. may be very long.For example,
One customary DC unit is run with 1000MW, and the unlock of another customary DC unit, dispatching the power regulation rate assigned is
5MW/min, then 2. process is then up to 80min.If in this process, such as tx moment, power-management centre requirement promotion function
Rate then still will appear the case where two customary DC cell powers successively reach power target value, second half section power rise speed
The problem of rate halves, dispatch curve implementation deviation.
For this purpose, prioritization scheme provided in an embodiment of the present invention is mainly to increase the time of power-balance, to two routines
Power is gone up and down again after the power complete equipilibrium of direct current component, in this way, it is successive to avoid the occurrence of two customary DC cell powers
The case where reaching power target value, the problem of effectively evading dispatch curve implementation deviation.Below to the embodiment of the present invention program
It is illustrated.
It is gone up and down referring to the double cell powers for shown in Fig. 1-4, providing a kind of Asynchronous Interconnection engineering in one of the embodiments,
Rate optimized method.As shown in Figs 1-4, double cell power ramp rate optimization sides packet of the Asynchronous Interconnection engineering in the present embodiment
Include following steps:
Step S101: after two customary DC unit ingoing power equilibrium process of Asynchronous Interconnection engineering, to be preset with
Function coordinates rate value and carries out power regulation to described two customary DC units；
Here, 2. the power balancing procedure of two customary DC units of Asynchronous Interconnection engineering refers to the process of in Fig. 1-2.
Here, the size for presetting active coordination rate value can be set according to actual needs, but generally to choose to the greatest extent
Big value is measured to be preferred, so that the power of two customary DC units reaches balance as early as possible, reach here balance refer to two often
The performance number for advising direct current component is equal.In practical applications, 300MW/min can be selected to preset active coordination rate as this
Value, but preset the active specific value for coordinating rate value and be also not necessarily limited to this.
Step S102: if with preset active coordination rate value to described two customary DC units carry out power regulation it
After receive power lifting instruction, then obtain from start with preset active coordination rate value to described two customary DC units into
Row power regulation goes up and down the duration of instruction to power is currently received；
Specifically, after to preset active coordination rate value to described two customary DC units progress power regulation,
It detects whether to receive power lifting instruction, if testing result is straight to described two routines to preset active coordination rate value
Stream unit carries out receiving power lifting instruction after power regulation, then obtains from starting to preset active coordination rate value to institute
It states two customary DC units and carries out power regulation to the duration for being currently received power lifting instruction.
Step S103: if the duration is less than the power of preset first time threshold and described two customary DC units
Value is not yet equal, then keeps to preset active coordination rate value to described two customary DC units and carry out power regulation until institute
The performance number for stating two customary DC units is equal, after the performance number of described two customary DC units is equal, according to described
The described two customary DC units of ramp rate set value calculation in power lifting instruction carry out power lifting；
Here, the size of the first time threshold can be set according to actual needs, but need to guarantee that two routines are straight
The performance number of stream unit reaches balance enough in first time threshold, i.e., adjusts the power to two customary DC units enough
It is worth equal.
Specifically, two customary DC lists of the size of the duration more described first and preset first time threshold and detection
Whether the performance number of member is equal, if the duration is less than the function of preset first time threshold and described two customary DC units
Rate value is not yet equal, then keep with preset active coordinations rate value to described two customary DC units carry out power regulation up to
The performance number of described two customary DC units is equal, after the performance number of described two customary DC units is equal, according to institute
The described two customary DC units of ramp rate set value calculation stated in power lifting instruction carry out power lifting.
In practical applications, the value of first time threshold is to be greater than each customary DC unit in power balancing procedure
The maximum power value for needing to shift is preferred with the active ratio for coordinating rate value is preset, to guarantee set first time threshold
It is adapted to all power-balance situations.For example, the performance number of one customary DC unit is 0MW in the case of most extreme,
The performance number of another customary DC unit is 1200MW, when balance each customary DC unit 600MW, that is to say, that in power
The performance number for needing to shift in equilibrium process is 600MW, and divided by 300MW/min, the time is 2min, and first time threshold should be big
In 2min, for example, 150s can be taken as, wherein needing the performance number shifted in most extreme situation is to need to shift most
High-power value.
Accordingly, according to the scheme in above-mentioned the present embodiment, be Asynchronous Interconnection engineering two customary DC units into
After entering power balancing procedure, power regulation is carried out to preset active coordination rate value to described two customary DC units, if
Power lifting instruction is received after this, then is obtained from starting to preset active coordination rate value to described two customary DC lists
Member carries out power regulation to the duration for being currently received power lifting instruction；If the duration is less than preset first time threshold
And the performance number of described two customary DC units is not yet equal, then keeps to preset active coordination rate value to described two normal
It advises direct current component and carries out power regulation until the performance number of described two customary DC units is equal, in described two customary DCs
After the performance number of unit is equal, according to the described two customary DCs of ramp rate set value calculation in power lifting instruction
Unit carries out power lifting, that is to say, that in this embodiment scheme after two customary DC unit ingoing power equilibrium process,
It is to be less than the first time threshold to preset active coordination rate value to described two customary DC units and carry out power regulation
Even if receiving power lifting instruction in the period of value, the ramp rate setting value that will not be gone up and down in instruction with power carries out function
Rate goes up and down and is to continue with to preset active coordination rate value to described two customary DC units and carry out power regulation until described
The performance number of two customary DC units is equal to carry out power lifting again, in this way, two customary DC units can be avoided the occurrence of
Power successively reaches the case where power target value, effectively evades schedule power curve implementation deviation problem.

Rate optimization method can also include:
Step S104: if the duration is not less than the first time threshold, according in power lifting instruction
The described two customary DC units of ramp rate set value calculation carry out power lifting.
In the present embodiment, since the first time threshold is to complete function according to two customary DC units of guarantee enough
The setting of rate equilibrium process, therefore, if (i.e. duration is not less than the first time threshold) receives function after this time
Rate lifting instruction, then can be directly straight according to the described two routines of ramp rate set value calculation in power lifting instruction
It flows unit and carries out power lifting.
