Design for automatic switching control of CEFR redundant electric system

Redundant design is fully considered in CEFR design, so some redundant equipment will have automatic switching requirements. A complete set of equipment (several electric control equipment) will fulfill a function together and indispensably. In design of such complex control requirements with interlock between equipment, safety, stability and human factors, as well as many other requirements shall be fully considered for the design and development work. Multiple interlocks between electric drive, software programming and host computer, and comprehensive considerations shall be adopted in design. Through comprehensive design integrated with hardware and software, the safety of equipment, and reliability of systems are improved to a maximum degree. In operation of fast reactor, automatic switching functions properly, and equipment runs well. (authors)
