Research On Intelligentizing Of High Voltage Equipment In Smart Power Station

With the rapid development of the world's economical society, the size of power grid in the world is expanding too. The risk of latency and uncertainty of power safety is developing. The quality and reliability in power supply is becoming higher and higher for users. By the beginning of 21 century, with the development of Smart Grid in the the Occident, the power industry in the world is becoming high reliability, high quality and green. State grid issued the report of Smart Grid layout, including power produce, power transmit, power transformation, power distribution, power consume and power dispatch.Smart station is the important part of Smart Grid layout. The Smart station will become the mainstream and will become more development. The high voltage of equipment is the basic unit in a power station, the smart high equipment (as smart equipment) is main part of power station. It is different from traditional station. The definition and criterion on smart equipment is not unified.The requirement on smart station is different in different phase. The requirement on smart equipment is different too. The mode of "high voltage equipment+smart unit" is the mainstream.The automatic real time measurement of state and parameter of the high voltage equipment by sensor is the base of smart high voltage equipment., and is the main method of smart high voltage equipment in the beginning of smart station. The method of high voltage equipment and smart unit will become intelligentize in high voltage equipment.By the project of 500kV Lanxi power station intelligentizing, the method and scheme is established. The curse and characteristic of technology is dissertated. The achievement is analyzed after the project.The method of high voltage equipment and smart unit is proved by the practice. With the development of equipment factory, and the use of device of online measurement device the smart equipment is becoming more compact. The real compact integrative smart equipment will be produced soon after the confusion of high voltage device model.
