Background technique
Along with non-renewable energy resources worldwide face exhausted awkward situation, for satisfying industrialized production with the human lives is required, people are to the concern of solar energy, wind-force, these renewable energy sourcess of waterpower and utilize lifting day by day.Wherein, wind-power electricity generation receives the extensive attention of various countries as a kind of developmental technology of new energy resources of maturation relatively that developed.
Variable blade control system is one of core component of wind power generating set; Its major function is the angle of coming regulator generator group blade according to the size of wind-force; Change the angle of attack of air-flow to blade; The output power of wind-driven generator can be automatically adjusted according to the size of wind speed, guarantee that the delivery efficiency of wind-driven generator is the highest, and output is in rated power.At present, the pitch-controlled system of China's wind-power electricity generation group adopts the direct current pitch-controlled system more, and what promptly the driver element of pitch-controlled system adopted is dc driver and direct current generator.The ubiquitous problem of direct current pitch-controlled system is that the specific power of direct current generator is little, cost height, troublesome maintenance etc.Current, wind power generating set per kilowatt cost continues to reduce, and falls over a large area cost at wind power plant, improves under the overall situation of cost performance, and the above-mentioned shortcoming of direct current pitch-controlled system is also just more outstanding.The driver element that exchanges pitch-controlled system adopts AC motor and ac driver.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 generator.Exchange the application of pitch-controlled system in wind power pitch-controlled system also more and more widely.Compare the direct current pitch-controlled system; The shortcoming that exchanges pitch-controlled system is; In a single day system breaks down; Exchange pitch-controlled system and can not utilize the reserve DC electrical source (generally being battery pack or super capacitor group) of pitch-controlled system directly to put away the oars, and the direct current pitch-controlled system can directly be added to the reserve DC electrical source on the direct current generator and puts away the oars.How improving the reliability that exchanges pitch-controlled system, is the most important thing that exchanges the pitch-controlled system development.
Wind power pitch-controlled system generally all comprises a main control unit and three performance elements.The core component of main control unit is PLC and module groups thereof, and PLC is the brain and the command center of whole pitch-controlled system.The core component of three performance elements is variable pitch drivers, the direct current pitch-controlled system with exchange pitch-controlled system, variable pitch driver adopts dc driver and ac driver respectively.Under the normal condition; The working procedure of pitch-controlled system is: PLC cooks up the velocity curve that becomes the oar motor according to the physical location and the target location of blade; Velocity curve sends to the analog sampling port of variable pitch driver through the analog amount form; The speed given curve that variable pitch driver is sent according to PLC drives and becomes oar motor speed operation with closed ring, makes blade arrive the target location fast.In the direct current pitch-controlled system, in case PLC breaks down, system is the starting theft-resistant link chain loop of promptly putting away the oars automatically: directly be added to the reserve DC electrical source on the direct current generator and put away the oars.Exchange pitch-controlled system and obviously can't realize this function (the reserve DC electrical source can't directly be supplied power to AC motor), exchange pitch-controlled system like this and just lacked an important point of safes, reduced safety coefficient.
