600 MW Power Plant Electrical Condition Monitoring Research And Practice

With modern power grid interconnection and grid structures more complex,power for each power supply and link reliability also have higher requirements.Under the premise of not increasing power equipment,improve the reliability of existing equipment can improve the reliability of power supply equipment,power system safe and stable operation.In the power plant,the principal means to improve power supply reliability of power plant systems is the basis of power supply units for maintenance,in order to improve the reliability of power supply system as a whole.How efficient and safe maintenance,is now a research direction,current maintenance for the bud of electrical equipment and power plant is not able to prevent it.Online condition monitoring system for real-time status of electrical equipment can be evaluated through mastering the real-time status of the electrical equipment,security status from its runtime,can be implemented in front of the equipment fault corresponding measures,eliminate security risks,to prevent electrical accidents.Based on the actual device is configured to 600 MW thermal power plant premises,acquisition information detected by the real-time status of each of these devices,and to analyze the collected status information,treatment,study on on-line condition monitoring of power plant equipment,and its main tasks are as follows:Firstly,according to 600 MW thermal power plant of transformer structure,design including transformer oil,and casing,and iron core,and winding,and clip pieces,and neutral points,and points received switch,and breathing device,and cooling system,of online state monitoring system;according to transformer of signal collection and flows,design easily operation of information collection system and work platform;last to a actual of transformer butterfly valve almost not open Shi of hot like monitoring case,description in actual run in the online state monitoring system is how prevention fault,and Transformer maintenance and care of the guidance.Then,online monitoring system for generator,online monitoring of generator monitoring devices in the system and a description of the monitoring information because of infrared thermal imaging the immediacy,and finally in infrared thermal imaging surveillance systems,for example,introduced in the actual operation of the online monitoring and fault prevention the information how to apply a description of the specific condition.Lastly,design circuit breaker device,and isolation switch,and arrester and other capacitor type equipment of monitoring system and its signal process;last to hot like temperature visits system image intuitive of description circuit breaker device internal contact bad,and isolation switch edge pressure received bad,and arrester copper tablets damp Shi of monitoring State,description online state monitoring system in actual application in the can up to prevention fault,and accident of role.
