Description
Technical field
The present invention relates to wind-driven generator, specifically is a kind of control system of wind-driven generator safe operation.
Background technique
Wind-driven generator be a kind ofly will clean, device that reproducible wind energy is transformed into electric power kinetic energy, it is made up of a plurality of parts, control system then is through to each part, is equivalent to the nervous system of wind-driven generator.Therefore the quality of control system is directly connected to working state, generated energy and the device security of wind-driven generator.
At present; The control system of wind-driven generator mainly is made up of master control system, slip ring and pitch-controlled system etc.; Instructions such as the powering on of wind-driven generator, standby, startup, generating and shutdown are carried out by the master control system of core; These instructions flow to pitch-controlled system by slip ring, are specifically realized by its inner axle control cabinet, servo driver and motor of pitch-controlled system control.In order to ensure the normal operation of wind-driven generator, on master control system, be connected with the master control theft-resistant link chain, this theft-resistant link chain comprises control power supply and state relay, the control power supply is 24VDC, and is given by master control system; The normally opened contact of state relay is connected the output terminal of master control system, on the state relay, is in series with emergency stop switch, driftage switch, overspeed detection switch, vibration switch etc. successively; These switches occur when unusual at the object that is detected; Its normally opened contact breaks off; The state relay breaks off the back power down at arbitrary normally opened contact of being connected, and the normally opened contact of state relay also breaks off, and carries out urgent feathering and dead halt by master control system control pitch-controlled system.Yet; Because problems such as the rugged environment of wind energy turbine set, slip ring usually because reasons such as iron filings, dirt, water droplet, thunderbolt, vibrations break down, cause the control signal of its transmission to be short-circuited, open circuit; Can't be to the correct control command of pitch-controlled system transmission; Pitch-controlled system is feathering excision wind energy in time just also, this direct threats the safety of wind-driven generator, lead to serious accident easily.
Summary of the invention
The objective of the invention is to: to the deficiency of above-mentioned existing technology; A kind of wind-driven generator safe operation control system is provided; This control system is the change oar theft-resistant link chain of on the basis of existing control system, having set up an association and being independent of the master control theft-resistant link chain; Make the two form Redundancy Design, guarantee the operation that wind-driven generator can be safe and reliable.
The technological scheme that the present invention adopts is: a kind of wind-driven generator safe operation control system; Comprise master control system, slip ring and pitch-controlled system; Be connected with the master control theft-resistant link chain on the said master control system; This master control theft-resistant link chain can threaten each electric elements of outside and the running state of the normal operation of wind-driven generator to monitor with opposing; When arbitrary electric elements of master control theft-resistant link chain monitoring and running state occur when unusual, the master control theft-resistant link chain sends state signal to master control system, controls pitch-controlled system by master control system and carries out urgent feathering and dead halt; Said pitch-controlled system has a theft-resistant link chain; This theft-resistant link chain is independent of the master control theft-resistant link chain; Become oar theft-resistant link chain state output end and be connected in the pitch-controlled system signal input part, this signal input part is accepted the safe condition control signal that master control system is transmitted to pitch-controlled system, becomes the oar theft-resistant link chain and can threaten inner each running state of pitch-controlled system of the normal operation of wind-driven generator to monitor with opposing; When the arbitrary running state that becomes the monitoring of oar theft-resistant link chain occurs when unusual; Pitch-controlled system ACTIVE CONTROL blade carries out urgent feathering, and will become oar theft-resistant link chain status information and in time feed back to master control system through slip ring, is shut down by other subtense angle emergency safety of master control system control.
Said change oar theft-resistant link chain comprises control power supply and state relay K 2; The normally opened contact K2 of said state relay K 2 is connected in the pitch-controlled system signal input part, on state relay K 2, is in series with the change oar successively and detects over speed switch, axle 1 driver switch, axle 2 driver switch, axle 3 driver switch, change oar controller switches and become the oar maintenance switch; Said change oar detects over speed switch normally opened contact when detecting wind driven generator principal shaft rotation hypervelocity and breaks off; Said axle 1 driver switch normally opened contact when axle 1 driver malfunction breaks off; Said axle 2 driver switch normally opened contact when axle 2 driver malfunctions breaks off; Said axle 3 driver switch normally opened contact when axle 3 driver malfunctions breaks off, and said change oar controller switches becomes the oar controller and occurs that normally opened contact breaks off when unusual detecting, and said change oar maintenance switch normally opened contact when blade is safeguarded breaks off; Said state relay K 2 is broken off the back power down at arbitrary normally opened contact of being connected; Its normally opened contact K2 breaks off, the urgent feathering of pitch-controlled system ACTIVE CONTROL blade, and will become oar theft-resistant link chain status information and in time feed back to master control system through slip ring.
Said change oar theft-resistant link chain also comprises a reset relay K3 parallelly connected with state relay K 2; This reset relay K3 is when powering on; During all normal adhesive of its normally opened contact K3 adhesive, the status switch of being monitored when state relay K 2, and then make state relay K 2; The normally opened contact K2 adhesive of state relay K 2 automatically resets change oar theft-resistant link chain; Be in series with blade 1 feather position switch, blade 2 feather position switches and blade 3 feather position switches on the said reset relay K3 successively; Said blade 1 feather position switch is the normally opened contact adhesive when detecting blade 1 arrival feather position; Said blade 2 feather position switches are the normally opened contact adhesive when detecting blade 2 arrival feather position; Said blade 3 feather position switches are the normally opened contact adhesive when detecting blade 3 arrival feather position, and said reset relay K3 powers on after all normally opened contact adhesives of being connected.
The invention has the beneficial effects as follows: above-mentioned control system has been set up change oar theft-resistant link chain; This theft-resistant link chain and master control theft-resistant link chain form related and Redundancy Design independently; Given pitch-controlled system certain independence, become the oar theft-resistant link chain just often, pitch-controlled system is carried out the control command that master control system is transmitted through slip ring; Arbitrary running state in becoming the oar theft-resistant link chain occurs can carrying out urgent feathering by the ACTIVE CONTROL blade when unusual; And simultaneously status information is in time fed back to master control system through slip ring, and need not the master control system control command of waiting for that slip ring transmits, a series of negative consequences of having avoided the slip ring fault to be brought greatly; Effectively improved the Security of wind-driven generator, its reliability is high, practical.
In addition, the present invention becomes the oar theft-resistant link chain and when all normal adhesive of the status switch of being monitored and all blades all are in feather position, can automatically reset.Automaticity is high, has alleviated labor strength, efficient quick.
