Huaneng Jinghong Hydropower Station Crane Localization Control System Transformation Project Successfully Accepted

Recently，Huaneng Jinghong Power Plant Bridge Crane Control System Renovation Project, which is implemented by the Small and Special Hydropower Division, has completed commissioning and put into operation smoothly according to the established objectives.，It has passed the acceptance of Jinghong Quality and Technical Supervision Bureau at one time.。

Two 660-ton bridge cranes in the main workshop of Jinghong Power Plant，It is mainly used to lift the rotor of hydraulic Generator unit.、Runner, etc。At present, the bridge crane in the main powerhouse has been put into operation for about 15 years.，Secondary components enter the aging period，Increased failure rate，It not only restricts the maintenance period of the unit，And there are potential safety hazard in that major lifting operation of the unit maintenance.。

The construction period of the project is just in the period of the National Day and the twenty major power conservation tasks.，In order to fulfill the task of protecting electricity，Under the high attention of leaders at all levels of the power plant，The members of the Project Department shall carry out construction in strict accordance with the technical requirements，Completed the project efficiently。

Face the time pressure，The epidemic situation is lockdown，There are many factors such as tight delivery of some components and high temperature weather on site.，The site construction project department shall proceed from the actual situation of the project.，Actively communicate and coordinate with the team，The team shall assign a special person to supervise，Detailed deployment of the work in the transformation，Work out the work plan scientifically，Work overtime to complete the key control nodes of the plan in the transformation work，The bridge crane transformation project was successfully completed.，It has overcome many difficulties on site.，The renovation work was completed on schedule.。

All the renovation projects are localized.PLCThe controller is used as the core control component，It replaces the original imported products.，It is the first time to be used in the linkage control system of bridge crane and two Vehicles.，Through continuous testing and optimization，The operation is stable and reliable。Replace all the original rectification feedback control units with frequency conversion control units.，Multiple control modes of one-control-one and one-control，The multi-mechanism redundant control is realized.，It provides a reliable guarantee for the emergency operation of bridge crane.。The project not only achieved a hardware upgrade，It also upgrades the control system program.，The multi-mechanism automatic operation function of the bridge crane is realized.，By 3D coordinate command，And realize that automatic and accurate positioning of the bridge crane.。

The successful completion of the project，It provides reliable technical support for unit maintenance and hoisting.，It provides a reliable guarantee for the safe operation of the equipment in the later period.。

So，Jinghong Power Plant expresses its heartfelt thanks to Weite Technology Co., Ltd.。Pay tribute to the front-line technical engineers struggling in Jinghong Power Plant，You are all good.！It is you who are sweating on the construction site.，Show the spirit of Weite from the details.，Through hard work.，Finally, it won the praise of customers.。
