Reactor circulating pump system |
摘要 |
A reactor circulating pump system comprises a pump and a power supply apparatus for driving the pump. In the power supply apparatus, an AC/DC converter and a DC/AC converter provided with an AC voltage/frequency adjuster are connected in series between an in-plant AC bus and a reactor circulating pump, a DC voltage adjuster, a superconducting energy storage apparatus and an excitation power supply source are connected to the input side of the DC/AC converter. A controller is incorporated in the power supply apparatus so as to receive a signal indicating instantaneous power failure or power breakdown on the in-plant AC bus, or reactor trip, and change an AC voltage supplied to the reactor circulating pump with a ratio of AC voltage and frequency kept constant for controlling a pump delivery rate to have a predetermined value, while holding an output voltage from the superconducting energy storage apparatus at a predetermined value.
