Comprehensive testing device and testing method of double-fed wind power generator set

Abstract

The invention discloses a comprehensive testing device of a double-fed wind power generator set. The device comprises a power generator cabinet, a joint debugging control cabinet and a driving frequency conversion cabinet, wherein the joint debugging control cabinet and the driving frequency conversion cabinet are fixedly installed at the top of the power generator cabinet, a driving frequency converter is arranged in the driving frequency conversion cabinet, and the output end of the driving frequency converter is connected with a cable used for being connected with the wiring end of the stator side of a double-fed wind power generator; a debugging system PLC and a driving system PLC are installed in the joint debugging control cabinet, the debugging system PLC is in communication connection with a cabin PLC and a variable-pitch PLC, and the driving system PLC is in communication connection with the driving frequency converter; and a transformer used for power supply voltage reductionis further installed in the joint debugging control cabinet, and a cabinet door of the joint debugging control cabinet is further provided with a touch screen which facilitates command input and information display. The device is reasonable in design and complete in function, and can carry out static debugging and driving tests on the wind power generator set in a power-action-free interval, thetest efficiency is high, so that the generator set can be guaranteed to be safely and rapidly put into use.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a comprehensive test device for a doubly-fed wind power generating set, and also relates to a testing method for the above-mentioned comprehensive testing device for a doubly-fed wind power generating set. Background technique [0002] The joint debugging and testing technology of wind turbines is a key technology in the field of wind power, and it is also a weak link of domestic wind power manufacturers. The existing joint commissioning test of wind turbines requires a stable power supply, which limits the joint test site to a fixed place with power supply such as the production test workshop, which greatly limits the application of joint test technology in wind farms, wind turbines, etc. For applications in places without stable power supply, such as warehouses and open-air sluggish unit yards, if it is necessary to conduct joint commissioning tests in the above p...

Problems solved by technology

The existing joint commissioning test of wind turbines requires a stable power supply, which limits the joint test site to a fixed place with power supply such as the production test workshop, which greatly limits the application of joint test technology in wind farms, wind turbines, etc. For applications in places without stable power supply such as warehouses and open-air sluggish unit yards, if it is necessary to conduct joint commissioning tests in the above places, it will take a lot of manpower and material resources to arrange power supply devices and cables, which will increase the additional production costs of wind turbines.

[0003] The commissioning test of the wind turbine needs to carry out static commissioning and dragging test, but the existing commissioning test technology separates the static commissioning and dragging test of the wind turbine, and needs to use two sets for static commissioning and dragging test respectively. The test device and operation method are complicated to operate, and there are great safety hazards when switching between different test devices
