Abstract
The utility model relates to a power electronic device controlled by an off-grid wind turbine generator system and specifically relates to a current-converting and energy-storing control device of an off-grid wind turbine generator system. The device comprises multiple rectifiers, DC/DC devices, and an inverter. The multiple rectifiers are connected with a wind turbine generator set respectively and share one DC bus L. The number of the DC/DC devices is the same as that of the wind turbine generator sets. The input ends of the DC/DC devices are connected with the DC bus, while the output ends of the DC/DC devices are connected with an energy-storing source, respectively. The input end of the inverter is connected with the DC bus L, while the output end of the inverter supplies power for a load. The current-converting and energy-storing control device is capable of supplying power for multiple wind turbine generator sets and satisfies a requirement for large-power power supply. The output part of the current-converting and energy-storing control device supplies power for the load with the inverter and multiple DC/DC devices connected in parallel are simultaneously applied to a DC side. Therefore, a problem of grid-connected synchronism is resolved effectively and stable power can be provided.
Description
Technical field
The utility model relates to from the power electronic equipment of net type wind powered generator system control, specifically is a kind of unsteady flow and energy storage control device from net type wind generator system.
Background technology
Wind energy is being played the part of more and more important painted in current society as a kind of regenerative resource of green, the development blower fan that is incorporated into the power networks on a large scale is more and more general in various countries.Yet, the grid structure design of a lot of national grids is unreasonable, the electricity transportation that the Large scale construction wind energy turbine set causes a lot of blower fans to be incorporated into the power networks or to send is not gone out, and this has wasted the wind-powered electricity generation resource greatly and caused the wind-powered electricity generation net fluctuation to occur and has seriously influenced the load electricity consumption.At such problem, development possesses very important real applying value from net type blower fan.Has good utilization prospect equally at remote village, island or big energy-dissipating type equipment etc. simultaneously.
At than heavy load, when general separate unit blower fan can't meet the demands, adopt many typhoons power generator group at sending end powering load in parallel, such simplicity of design satisfies the power reguirements requirement of load easily.But there is more problem in the parallel connection of many unit sending ends: have the stationary problem that is incorporated into the power networks when at first the second typhoon machine is in parallel, there was circulation problem in the inversion end, is difficult to guarantee two typhoon machine constant power operations etc. again when secondly many units were in parallel.201220081588.4), non-grid connected wind power device for producing hydrogen (application number: 201220081602.0) two pieces of patent documentations existing relevant patent documentation comprises: non-grid connected wind power sea water desalinating unit (application number:, in these two pieces of patent documentations, all make blower fan from network operation, be used in sea water desalinating unit and hydrogen manufacturing aspect respectively and handle.The problems that these structures do not have consideration to exist when many typhoons machine is in parallel under the heavy load situation.
The utility model content
Technical problem to be solved in the utility model is that a kind of unsteady flow and energy storage control device from net type wind generator system that influence is little, the synchronism that is incorporated into the power networks is good that can be applicable to that many typhoons group of motors powers, is subjected to many typhoons machine operate power to change simultaneously is provided.
Unsteady flow and energy storage control device from net type wind generator system of the present utility model includes:
A plurality of rectifiers that are connected with a plurality of wind-powered electricity generation units respectively, described a plurality of rectifiers share a dc bus;
The DC/DC device that quantity is identical with wind-powered electricity generation unit quantity, the input of each DC/DC device all connects described dc bus, and its output connects the energy storage source respectively;
An inverter, the input of described inverter connects described dc bus, and its output is the load power supply.
The utility model can be applicable to that many typhoons group of motors powers simultaneously, has satisfied the requirement of high-power power supply; Its output adopts an inverter powering load, increases many DC/DC shunting means in DC side simultaneously, has effectively solved the synchronism problem that is incorporated into the power networks, and stable power supply can be provided.
