Design For Lightning Protection Control System Of Yellow River Sluice Gate

Lightning is an instant discharge phenomenon occurs in nature, and accompanied bysound, light appears. Usually the first discharge process duration is0.1-1.0s. Generatinglightning reasons is a rise and downdraft thunderstorm convection movement, so that the cloudoriginally random distribution of positive and negative charge into the ordered arrangement ofthe structure, to form a positive charge and a negative charge region in the cloud. Thunderstormarea accumulated enough positive (negative) charge reached breakdown atmosphere, so that theelectric field strength in space or on the ground somewhere, it will produce lightning, asignificant impact on people’s lives and property as well as the natural environment.Strong convective weather is generally accompanied by intense lightning activity, oftencaused by lightning disasters, buildings and other facilities on the ground and even casualties.Significant increase since the1980s, with the large number of applications of high-techequipment, microelectronics devices, the harm caused by lightning, is extremely sensitive tolightning electromagnetic interference are closely related with the high-tech field, thewidespread adoption of large-scale and oversized scale integrated circuits, and greatly increasethe chance of lightning electromagnetic interference microelectronic devices work properly,and sometimes even cause serious equipment damage.Shandong Yellow River has a total of68yellow river water diversion. In order tostrengthen the management of water resources of the Yellow River to ensure the normaloperation of the industrial and agricultural water supply along the Yellow River, the state hasinvested more than3,000million for the51yellow river water diversion project to install aremote monitoring system, but because of their geographic Yellow River water diversionparticularity of location, natural conditions are very harsh, sluices remote monitoring systemsoften struck by lightning during the rainy season, the equipment was severely damaged, theeconomic losses, therefore, to promote mine work to ensure the smooth operation of the remotemonitoring system has a very important significance.This paper base on lightning meteorological the multivariate experts rule, real-timeacquisition of meteorological information as data in support of the control system, and learnfrom the expert system control method to achieve the lock chamber power lines automatically switching. Lightning protection control system uses ABB’s AC500-ECO PLC as the sceneworkstation, Wei Lun touch screen MT6070IH as a host computer. Lightning protection controlsystem achieves on-site environmental monitoring, device status monitoring, manual control/automatic control, remote SMS control and real-time alarm,history data storage. The system inthe lower reaches of the Yellow River in Shandong has been used in practical operation showsthat the security of the system, reliable, high degree of automation, simple operation, low cost,easy to maintain and realize the sluices remote monitoring system lightning protectioneffectively, has met the design requirements.
