Abstract
The invention relates to a wind power plant AGC control function realization method. The method comprises a scheduling data network and a motion communication apparatus connected with the scheduling data network. The motion communication apparatus is connected with a blower fan monitoring server, the blower fan monitoring server is connected with multiple blower fan PLC execution units, a gateway module is arranged between the motion communication apparatus and the blower fan monitoring server, the gateway module controls blower fan power through an active power control module arranged inside, and the active power control module distributes power generated by a blower fan, obtained by each blower fan monitoring server according to proportions. According to the invention, through adoption of the optimization improvement based on AGC control of a conventional wind power generator set, the capability of the set in responding to power grid frequency change is effectively improved. Besides, output of each set is effectively distributed.
Description
Technical field
The invention belongs to Automatic Generation Control technical field, particularly a kind of wind energy turbine set AGC automatic control function realizes method.
Background technology
Greatly developing of the regenerative resources such as wind-powered electricity generation is advantageously implemented China's energy structure optimizing adjustment, promotes power system energy-saving and emission-reduction, but the undulatory property of wind-powered electricity generation, uncertainty and inverse peak regulation also bring problems to safe and stable operation.Wind energy turbine set should possess active power regulation ability, controls the output of its active power according to dispatching of power netwoks departmental instruction.Realizing the control to active power, wind energy turbine set should configure meritorious power control system, receives and automatically performs the active power controller signal that a traffic department distant place sends.Sufficient competition when for giving full play to wind-electricity integration, between the interior AGC unit of net.
Current existing wind-powered electricity generation AGC system is as it is shown in figure 1, include dispatching data network, telemechanical communicator, fan monitoring server and the multiple blower fan PLC performance elements being connected with fan monitoring server.Wind energy turbine set AGC causes, due to the polytropy of wind energy resources, the randomness that every Fans exerts oneself, and causes the uncertainty that wind power integration afterload fluctuates.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, and propose a kind of wind energy turbine set AGC automatic control function and realize method.
This invention address that it technical problem is that takes techniques below scheme to realize:
A kind of wind energy turbine set AGC automatic control function realizes method, including dispatching data network, the telemechanical communicator being connected with dispatching data network, telemechanical communicator is connected with fan monitoring server, fan monitoring server is connected with multiple blower fan PLC performance elements, gateway machine module it is connected between telemechanical communicator and fan monitoring server, gateway machine module is responsible for by internal active power controller module, power of fan is controlled, the active power controller module system to there being 2 or more than 2 fan monitoring servers, it it is the input of the passing ratio factor, the power that the blower fan obtained by each fan monitoring server produces is allocated in proportion.
And, the power that the blower fan that each fan monitoring server is obtained by the passing ratio factor produces is allocated in proportion method particularly includes:
1. being recorded, by power-measuring device, the different capacity that current every Fans produces, power data enters active power controller module；
2. being set between 0.4～0.7 by scale factor, input scale factor is to active power controller module, and power control module adopts and adjusts blower fan current power in the control mode of difference ratio Approach by inchmeal desired value, it is ensured that control the flatness of process work rate curve.
Advantages of the present invention and having the benefit effect that
The AGC control function of active service wind power generator group examines checking through repeatedly united test and longtime running after taking Optimal improvements of the present invention, and the ability of unit responsive electricity grid frequency change is effectively improved.Exerting oneself of every unit effectively distributes.

Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described: it is emphasized that; embodiment of the present invention is illustrative; rather than it is determinate; therefore the present invention is not limited to the embodiment described in detailed description of the invention; every other embodiment drawn according to technical scheme by those skilled in the art, also belongs to the scope of protection of the invention.
A kind of wind energy turbine set AGC automatic control function realizes method, as shown in Figure 2, including dispatching data network, the telemechanical communicator being connected with dispatching data network, telemechanical communicator is connected with fan monitoring server, fan monitoring server is connected with multiple blower fan PLC performance elements, the innovative point of the present invention is, gateway machine module it is connected between telemechanical communicator and fan monitoring server, gateway machine module is responsible for by internal active power controller module, power of fan is controlled, the active power controller module system to there being 2 or more than 2 fan monitoring servers, it it is the input of the passing ratio factor, the power that the blower fan obtained by each fan monitoring server produces is allocated in proportion.
In specific embodiment of the invention, as it is shown on figure 3, what the power that the blower fan that each fan monitoring server is obtained by the passing ratio factor produces was allocated in proportion method particularly includes:
1. being recorded, by power-measuring device, the different capacity that current every Fans produces, power data enters active power controller module,
2. being set between 0.4～0.7 by scale factor, input scale factor is to active power controller module, and power control module adopts and adjusts blower fan current power in the control mode of difference ratio Approach by inchmeal desired value, it is ensured that control the flatness of process work rate curve.Scale factor is set in 0.4～0.7, such as current power is 100MW, desired value is 50MW, set scale factor as 0.6, then the 1st regulated value is (100-50) * 0.6=30MW, with wind speed constant when, after adjustment, realtime power is 70MW, then the 2nd regulated value is (70-50) * 0.6=12MW, by that analogy, and Step wise approximation desired value.It is effectively accomplished the function of power of fan reallocation.
