Abstract
The utility model provides a megawatt wind generating set full power testing stand vibration monitoring protection device. An acceleration vibration sensor is respectively installed on a detected megawatt wind generating set and a full power testing stand. The wind generating set is equipped with a plurality of limitators respectively equipped with horizontal direction and vertical direction limit switches. The acceleration vibration sensors and the limitators are connected with a PLC programmable controller of a main control system. The PLC programmable controller is connected with a main control PC. The megawatt wind generating set full power testing stand vibration monitoring protection device has a simpler structure, safely and reliably carry out protection on the full power testing stand and the detected wind generating set, and effectively avoids the wind generating set turning over and other safety accidents due to the excessive vibration.
Description
Technical field
The utility model relates to a kind of vibration monitoring device, particularly a kind of MW class wind turbine group full power trial (FPT) platform vibration monitoring protective device.
Background technology
In the prior art, Large-scale Wind Turbines manufacturing firm mostly has large-scale full power trial (FPT) platform.Carry out total power or approximate full power trial (FPT) at testing table.The principle of full power trial (FPT) is by powerful prime mover and current transformer, drags the aerogenerator operation, and can carry out stepless time adjustment.When speed reaches and during net spee, fan converter is connected to the grid aerogenerator, and after being incorporated into the power networks, by adjusting prime mover aerogenerator is moved under arbitrary speed, given given with power factor by the torque of regulating wind power current transformer, can realize the setting of any generated energy and power factor.
Double-feedback aerogenerator group full power trial (FPT) platform refers to set up on the ground the power test platform that carries out the various types test for the double-feedback aerogenerator group, on this test platform, can comprehensively test parts such as the gear case of wind power generating set, generator, current transformer, control system, check each parts whether can reach the requirement of standards and norms, avoid the part quality defective; Carry out designing technique and control algolithm checking for wind power generating set initial stage model machine, promote digesting and assimilating of technology, avoid design defect; Carry out new architecture exploitation or the alternative performance test of new parts research and development as development platform; As the platform of system debug, can debug and commissioning test personnel's training platform; Can also carry out the sampling observation test in when batch production in later stage.
Along with frequently coming into operation of high-power wind-driven generator group full power trial (FPT) platform, also often there are the accidents such as the rollover of test aerogenerator, testing table shaft coupling twist off to occur both at home and abroad.So it is particularly important that the vibration monitoring of testing table and protection become, avoid owing to shaking the security incident that causes to guarantee full power trial (FPT) platform and test wind power generating set.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of reasonable in design, safe and reliable, the MW class wind turbine group full power trial (FPT) platform vibration monitoring protective device being convenient to install are provided.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of MW class wind turbine group full power trial (FPT) platform vibration monitoring protective device, is characterized in: in tested MW class wind turbine group and full power trial (FPT) platform an acceleration shock sensor is installed respectively; Several are equipped with respectively the stop of horizontal direction and vertical direction limit switch to survey installation at aerogenerator; Described acceleration shock sensor, stop connects is connected with the PLC Programmable Logic Controller of master control system, and described PLC Programmable Logic Controller is connected with the master control PC.
In the MW class wind turbine group full power trial (FPT) platform vibration monitoring protective device technical scheme described in the utility model: the number of described stop can be selected as required, is preferably 3.
In this practical a kind of MW class wind turbine group full power trial (FPT) platform vibration monitoring protective device; by in tested MW class wind turbine group and full power trial (FPT) platform the acceleration shock sensor being installed; can detect respectively the oscillatory acceleration of aerogenerator and full power trial (FPT) platform in the process of the test, when the oscillatory acceleration value during greater than setting value the master control meeting receive alerting signal and carry out the dock reason.Several are equipped with respectively the stop of horizontal direction and vertical direction limit switch to survey installation at aerogenerator simultaneously; if there is the situation of vibration amplitude greater than the limit value of limit switch, the testing table master control system can receive alerting signal and carry out the dock reason in process of the test.The utility model equipment safety avoids wind power generating set to occur in process of the test owing to the vibrations reason causes the security incidents such as rollover reliably.
Compared with prior art; the utility model MW class wind turbine group full power trial (FPT) platform vibration monitoring protective device structure is more simple; it is protected full power trial (FPT) platform and tested wind power generating set safely and reliably, effectively avoids the generation owing to the security incidents such as wind power generating set rollover that cause of the excessive reason of vibrations.
