Generating set all possesses a set of runaway control system.Its control principle is：Normal braking and feathering behaviour can not be carried out in blower fan
When making, the rotating speed of impeller and generator is monitored in real time by the master controller of blower fan, judging the rotating speed of generator is
No hypervelocity, if hypervelocity master controller meeting automatic start yaw system occurs, yaw angle is the losing side of current face wind direction angle
To.Fan parking system of the prior art is single-link emergency shutdown system.If but occur in thunderstorm gale weather, cabin control
When shutting down runaway accident easily occurs for signal whole failure processed, the uncontrollable fan yaw of primary control program.With domestic wind-powered electricity generation row
The sustainable development of industry, southwest wind-powered electricity generation gradually increase, and west area wind power generating set is arranged in that physical features is open, height above sea level mostly
Area higher.Lightning strike accident occurred in strong wind thunderstorm weather, is present because thunderbolt causes control system failure to ultimately result in wind greatly
The accident potential of machine driving.
Wind generating set pitch control system control signal is to be reached instruction in wheel hub by slip ring by cabin master control system
Pitch-controlled system, if thunderbolt, which occurs, causes that master control system is stopped in fan engine room or slip ring failure causes communication disruption.Become
Oar system will be unable to receive instruction, realize that feathering is shut down.And under high wind conditions, it is difficult to shut down only by brake block, and therefore lead
Cause runaway accident.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of wind-driven generator feathering shutdown system, becomes in blower fan
Install two sets of independent pitch emergency stop devices in oar system additional, when failure occurs, master control system instruction, which realizes that feathering is shut down, prevents thunder
Hit driving.Meanwhile it will often cover change oar emergency stop device and be divided into outside jerk unit and internal jerk unit again, it is ensured that pitch-controlled system leads to
News smoothly become oar in the case of interrupting and shut down, and effectively prevent blower fan because thunderbolt causes the accident of driving to occur, ensure Wind turbine
Security.
The technical scheme that the utility model is taken is：
A kind of wind-driven generator feathering shutdown system, install two sets of independent pitch emergency stop devices additional in fan paddle-changing system,
Every suit independent pitch emergency stop device includes outside jerk unit and internal jerk unit；
First outside jerk unit includes being installed in parallel the first relay in each pitch control cabinet, any one
Pitch control cabinet triggers first set emergency shutdown process by the contact of the first relay.
Second outside jerk unit includes being installed in parallel the second relay in each pitch control cabinet, any one
Pitch control cabinet triggers second set of emergency shutdown process by the contact of the second relay.
First inside jerk unit is formed by the contact series for the 3rd relay being distributed in each pitch control cabinet,
When the 3rd relay contact in any one pitch control cabinet disconnects, fan paddle-changing system triggers first set emergency shutdown mistake
Journey.
Second inside jerk unit is formed by the contact series for the 4th relay being distributed in each pitch control cabinet,
When the 4th relay contact in any one pitch control cabinet disconnects, fan paddle-changing system triggers second set of emergency shutdown mistake
Journey.
A kind of wind-driven generator feathering shutdown system of the utility model, by above-mentioned two sets of independent pitch emergency stop devices, its
Inside and outside portion's jerk unit can be prevented effectively under extreme weather environment, because communicating interrupt causes blower fan feathering not shut down smoothly.
The single-link engine off control of instruction is sent by master control compared to tradition, reliability is higher.
