Background technology
Industrial automation is the spine of development of modern industry.Follow the develop rapidly of China's economic construction, all conglomerate automation equipments are widely used, and the situation that supply falls short of demand occurs.Yet, far do not reach the usefulness electric standard (voltage, frequency, harmonic components, noise etc., load capacity) of many high-end automation equipments in view of most domestic regional power supply supportability, cause many automation equipments to fail to give full play of its due task performance, the product quality fault appears in the serious situation, the delivery cycle passive receive is imposed a fine because not satisfying, equipment fault is frequent, maintenance cost is high.The unperturbed electric power system of a kind of high-power, multiple input energy sources of active demand.
At present, many industrial environments adopt common UPS as the auxiliary work power supply of crucial automation equipment, such as Fig. 1, there is series of problems in it, and for example single-machine capacity is little, operational efficiency is low, without the environment management function, and band integrated load ability, humorous wave interference is large, incompatible with the industrial DC power-supply system that the large scale industry system adopts, wherein especially, common ups system designs for the IT load characteristic, it is with inverter, and particularly dynamo-electric load capacity is poor for the band mixed load.In addition, UPS conduct independently parts is present in the electric power system, and system lacks the energy state integrated management function.
Summary of the invention
The invention will provide industrial unperturbed electric power system, and its high-quality power supply to load is uninterrupted, not be subjected to the particularly restriction of poor this shortcoming of dynamo-electric load capacity of inverter band mixed load of UPS, guarantee the high-quality power supply of load.
The invention provides industrial unperturbed electric power system, it is characterized in that, comprise that power supply arranged side by side is to internal combustion engine generating direct-furnish branch road, civil power direct-furnish branch road and the civil power energy storage inversion branch road of the first feeder line, between these three branch roads and the first feeder line, be connected to switching device shifter but be not connected to UPS, in civil power energy storage inversion branch road, civil power charges to energy storage device through charger, and energy storage device is given the first feeder line through inverter power supply.
The invention gives the control method to this industrial unperturbed electric power system, and it reduces cost so that industrial unperturbed electric power system can adopt the less energy storage device of capacity.
Control method to given industrial unperturbed electric power system, it is characterized in that, given under the state of the first feeder line by mains-supplied, in case civil power outage, just starting apparatus combustion engine and switching to by energy storage device through inverter power supply to the first feeder line is immediately powered to the first feeder line until internal combustion engine generating output normally then switches to by internal combustion engine generating direct-furnish branch road.
The invention has the following advantages:
(1) after the civil power outage, before interior combustion gas startup was finished, industrial unperturbed electric power system ran on energy storage inversion powering mode, and civil power energy storage inversion branch road can be powered to the first feeder line, guarantees the high-quality power supply of load uninterrupted;
(2) internal combustion engine is without inverter, and directly power supply is not subjected to the particularly restriction of poor this shortcoming of dynamo-electric load capacity of inverter band mixed load of UPS to the first feeder line, guarantees the high-quality power supply of load;
(3) in case civil power outage, just internal combustion engine generating direct-furnish branch road can be powered as early as possible to the first feeder line for starting apparatus combustion engine immediately, short to civil power energy storage inversion branch road power-on time demand, can adopt the less energy storage device of capacity, reduced cost.
