Background technology
Wind power generation receives the whole world day by day and extensively payes attention to as cleaning, abundant, regenerative resource, has particularly obtained this year developing rapidly; When the distinguished and admirable pneumatic equipment blades made of crossing; When driving the wind energy conversion system rotation, wind energy transformation is a mechanical energy, wind energy conversion system drawing generator rotor rotation again; Generator is to mains supply, and mechanical energy is converted into electric energy.
Along with the increase with separate unit wind-powered electricity generation unit capacity that increases that inserts the wind-powered electricity generation unit in the electrical network; Electric power system has had requirements at the higher level to the grid connected wind power unit operation; Wherein significantly still can keep under the AC network fault being connected with electrical network and to the electric power system continued power maybe, promptly have the ability that runs without interruption under the external fault.Because compare excitation variable frequency power supply capacity with generator rating power less; If do not take correct safeguard measure when under fault, running without interruption; Then can failover make the generator amature side induce big electric current; Cause the safety of rotor-side converter overcurrent and DC link overvoltage, serious harm wind-powered electricity generation unit core component, this is the practical problem that present domestic wind-powered electricity generation unit operation controller enterprise does not consider and must face in the design of wind-powered electricity generation unit.
Summary of the invention
The objective of the invention is to wind turbine generator of the prior art when electrical network breaks down; Overcurrent and overvoltage take place easily; Thereby the problem of serious harm wind turbine generator core component safety provides a kind of intelligent wind power power generation control, makes that the wind turbine generator operation is more reliable; Protect generating set, prolonged the useful life of generating set.
The objective of the invention is to realize like this: a kind of intelligent wind power power generation control; Comprise through circuit breaker and be connected the two PWM variators on the electrical network; Said pair of pwm converter also links to each other with the double-fed wind power generator group; The signal input part of said pair of pwm converter links to each other with the signal output part of dsp processor; The signal output part of said dsp processor also links to each other with the signal input part of GPRS wireless communication module, and said dsp processor also links to each other with fpga chip, and the signal input part of said fpga chip links to each other with the signal output part of data acquisition module; The signal output part of said fpga chip links to each other with the signal input part of PLC, and the signal output part of said PLC links to each other with the relay group.
As further improvement of the present invention, said dsp processor adopts the TMS320F28335 chip.
When the present invention worked, data acquisition module was gathered the on-the-spot operational factor of generating set, and will collect data and send to dsp processor through fpga chip; Dsp processor carries out processing operations to the data that collect; Send control corresponding again and instruct to fpga chip, fpga chip sends to PLC with control command again, PLC control relay group action again; Realize the order operation of generator; Dsp processor is uploaded to host computer with data message that collects and control command through the GPRS wireless communication module, the radio communication of realization and host computer, simultaneously; DSP gives two pwm converters according to the data parameters sending controling instruction that receives, the control generating set be implemented in be incorporated into the power networks and independent operating between carry out the switching action.Compared with prior art, beneficial effect of the present invention is that the present invention adopts dsp processor, fpga chip respectively as master controller, pilot controller; Realization is to real-time monitoring, the control operation of wind-driven generator operating state, and when electric network fault, wind turbine generator can automatically switch into independent operating; Avoid generating set to receive the influence that electric network fault brings, make that the wind turbine generator operation is more reliable, protected generating set; Prolonged the useful life of generating set; And the master-slave mode digital distribution control structure that adopts, the master control architecture of simplification has reduced equipment cost.The present invention can be used in the wind turbine generator.
