Abstract
The utility model discloses a redundancy power supply for a master control board of an alternative current driver. According to the utility model, the redundancy power supply is connected with a switch power supply; the input end of the switch power supply is connected with the bus of the alternative current driver; and the output end of the switch power supply is connected with the master control board of the alternative current driver. The redundancy power supply also comprises an external direct current power supply, wherein the input end of the external direct current power supply is connected with a UPS (uninterrupted power supply); and the output end of the external direct current power supply is connected to the output end of the switch power supply in parallel through a diode. The work power supply of the master control board of the alternative current driver eliminates the disadvantageous influences of a wind power grid through the power-supplying redundancy design of the external direct current power supply, thereby ensuring the normal work of the master control board of the alternative current driver part and improving the use reliability of the alternative current driver in a wind power alternative current variable propeller system.
Description
Technical field
The utility model belongs to wind power generation field, relates in particular to a kind of ac driver master control board redundancy power supply that wind-powered electricity generation exchanges pitch-controlled system that is used for.
Background technology
At present, the pitch-controlled system of China's wind power generation group adopts dc driver and direct current machine more, and the power density that its ubiquitous problem is a direct current machine is little, and high, the troublesome maintenance of cost, commutation brush are that wear-out part need regularly replace etc.Especially fall over a large area cost in the wind-powered electricity generation industry, improve today of cost performance, its shortcoming is more outstanding.
Ac motor structure is simple, reliability and durability, cost are low, easy to maintenance, has just in time overcome the above-mentioned shortcoming of direct current machine.The application in the wind electricity change paddle control system of ac driver and alternating current machine more and more widely.But the working power of ac driver control board is generally all produced by Switching Power Supply, and directly from the bus power taking of driver, bus is the electric network source rectification by the ac driver input to the Switching Power Supply input.Present stage, the quality of China's wind-powered electricity generation electrical network was not high, and harmonic wave is big, and EMC risks such as surge, electric voltage dropping and interruption are all bigger.
The utility model content
In view of the defective that above-mentioned prior art exists, the purpose of the utility model is to propose a kind of ac driver master control board redundancy power supply that wind-powered electricity generation exchanges pitch-controlled system that is used for.
The purpose of the utility model will be achieved through following technical scheme:
A kind of ac driver master control board redundancy power supply; Be connected in a Switching Power Supply; The input of said Switching Power Supply is connected with the bus of ac driver, and the output of said Switching Power Supply links to each other with the ac driver master control borad, also comprises an external dc power; The input of said external dc power is connected with a ups power, and the output of said external dc power is parallel to the output of said Switching Power Supply through a diode.
Preferably, above-mentioned ac driver master control board redundancy power supply, wherein: said diode is a clamp diode.
The working power of the utility model ac driver master control borad is through the Redundancy Design of external dc power power supply; Eliminate the adverse effect of wind-powered electricity generation electrical network; Guarantee the operate as normal of ac driver control section master control borad, improved ac driver and exchanged the reliability of using in the pitch-controlled system, the function of universal ac driver is increased and optimizes at wind-powered electricity generation; Make ac driver satisfy the specific (special) requirements of variable pitch driver; Application function strengthens, and performance improves, and satisfies at wind-powered electricity generation exchanging the application requirements in the pitch-controlled system more.
Following constipation closes the embodiment accompanying drawing, the embodiment of the utility model is done further to detail, so that the utility model technical scheme is easier to understand, grasp.
Description of drawings
Fig. 1 is the circuit diagram of the utility model embodiment 1.
Embodiment
Embodiment 1
