The power of drilling equipment is usually diesel or diesel generator set,not only consumes a lot of diesel,and diesel engine operation generated noise and exhaust pollution to the environment.In order to reduce drilling costs,improve drilling efficiency and efficiency,achieve energy-saving and emission reduction,cost reduction and efficiency increase,the use of industrial grid power supply for drilling power has been tested and promoted in domestic onshore oil fields.The power supply system of domestic drilling rig is 50 Hz,while some foreign countries use 60 Hz power supply.When domestic 50 Hz drilling rig equipment uses 60 Hz power grid in these foreign countries,it encounters different problems of power grid system,which brings inconvenience to the use of power grid in foreign operations.Adopting a high and low voltage power supply and distribution and variable frequency power supply system to convert foreign 35(10)kV,60 Hz power grid voltage into 600 V,50 Hz power grid voltage for domestic drilling rigs.
