Description
One, technical field: the present invention relates to the oil-field oil pumper power-saving technology, especially dynamically store Energy Saving Control cabinet and method of work
Two, background technology: the world today is faced with the energy environment problem; And the energy in the overwhelming majority oil pumper potential energy states process of present oil field all is to feed back to electrical network, and the energy of feedback is different because of voltage, harmonic wave, will bring very big impact to electrical network like this; Cause the electrical network service efficiency to worsen; Another kind of mode is to be converted into thermal energy consumption to fall, and so just causes the significant wastage of the energy, and research shows: the energy of feedback accounts for and consumes 30%-60% of gross energy in the oil pumper whole service process during oil pumper potential energy states; If can this part energy recuperation be used, will produce huge economic benefit and social benefit.
Three, summary of the invention: the purpose of this invention is to provide a kind of energy conversion efficiency height, free of contamination Energy Saving Control cabinet and the method for work dynamically stored; It has solved the energy resource consumption problem; The objective of the invention is to realize like this; It is to be formed by connecting energy-storage module group, energy storage parallel operation module groups, frequency converter, air switch, dc bus, motor, rectifier, inverter, and the energy-storage module group is connected with energy storage parallel operation module groups; Energy storage parallel operation module groups is connected with air switch; Air switch is connected by dc bus with frequency converter; Rectifier and inverter are installed in frequency converter; Frequency converter is connected with motor by electric wire.
Method of work of the present invention is: at first energy-storage module group, energy storage parallel operation module groups, air switch are together in parallel; And then be parallel on the frequency changer direct current bus; When the electrical network three phase mains gets into frequency converter; At first charge to the energy-storage module group through dc bus, when the energy-storage module group was filled to predetermined value, the inverter output end in the frequency converter just began externally to carry; Oil pumper is in operation, and unnecessary mechanical energy (containing potential energy, kinetic energy) can get into regenerative power generation state through drive motors, becomes direct current energy to be stored in the energy-storage module group to inverter converts Way of Regenerating Energy Feedback.The energy-storage module group is when absorbing feedback electric energy, and DC loop voltage rises slowly, can the electric energy of feedback be stored in effectively in the energy-storage module group; When drive motors does work, because the voltage of energy-storage module group is greater than the dc bus normal working voltage, therefore; What at first use is the electric energy that is stored in the energy-storage module group; When having only voltage in being stored in the energy-storage module group to be lower than the dc bus normal working voltage, system just can use the outer net power supply, therefore; The renewable energy resources by reuse timely and effectively when the motor powered state, thereby reach energy-conservation effect.
Meaning of the present invention is: the energy-storage module group has energy conversion efficiency height, pollution-free, characteristics such as maintainability good, energy storage density height.
Four, description of drawings: Fig. 1 is for dynamically storing the structural representation of Energy Saving Control cabinet, among the figure 1, energy-storage module group 2, energy storage parallel operation module groups 3, frequency converter 4, air switch 5, dc bus 6, motor 7, rectifier 8, inverter
Five, embodiment: embodiment 1, the present invention are formed by connecting energy-storage module group 1, energy storage parallel operation module groups 2, frequency converter 3, air switch 4, dc bus 5, motor 6, rectifier 7, inverter 8, and energy-storage module group 1 is connected with energy storage parallel operation module groups 2; Energy storage parallel operation module groups 2 is connected with air switch 4; Air switch 4 is connected by dc bus 5 with frequency converter 3; Rectifier 7 and inverter 8 are installed in frequency converter 3; Frequency converter 3 is connected with motor 6 by electric wire.
Embodiment 2, method of work of the present invention are: at first energy-storage module group 1, energy storage parallel operation module groups 2, air switch 4 are together in parallel; And then be parallel on frequency converter 3 dc buss 5; When the electrical network three phase mains gets into frequency converter 3; At first charge to energy-storage module group 1 through dc bus 5, when energy-storage module group 1 was filled to predetermined value, inverter 8 outputs in the frequency converter 3 just began externally to carry; Oil pumper is in operation, and unnecessary mechanical energy (containing potential energy, kinetic energy) can get into regenerative power generation state through drive motors 6, converts Way of Regenerating Energy Feedback to direct current energy to frequency converter 3 and is stored in the energy-storage module group 1.Energy-storage module group 1 is when absorbing feedback electric energy, and DC loop voltage rises slowly, can the electric energy of feedback be stored in effectively in the energy-storage module group 1; When drive motors 6 actings, because the voltage of energy-storage module group 1 is greater than dc bus 5 normal working voltages, therefore; What at first use is the electric energy that is stored in the energy-storage module group 1; When having only voltage in being stored in energy-storage module group 1 to be lower than dc bus 5 normal working voltages, system just can use the outer net power supply, therefore; The renewable energy resources by reuse timely and effectively when motor 6 motoring conditions, thereby reach energy-conservation effect.
