For the 1arge clients , such as lchu distributing bureau , scheme of fire fault prevention , which has high reliability in the mainframe system , is adopted . it heightens greatiy the stability and reliability of the system run 對于用戶數(shù)較多的蘭州供電局,設計主機系統(tǒng)為具有容錯能力的高可靠性異地容災方案,大大地提高了系統(tǒng)運行的穩(wěn)定性和可靠性。
Considering the above control strategies which make the controller can not be real - time processing because its workload has increased , control circuits of the main switches based on eprom are designed , which can implement control scheme of firing angles and phase voltage . furthermore , it avoids power converter saturation in the process of commutation 上述控制策略的引入造成控制器運算量增大、難以在線實時控制,又設計了基于eprom的主開關器件通斷控制電路,實現(xiàn)了開關磁阻電動機開通關斷角控制及對施加于相繞組上電壓的優(yōu)化控制,同時避免了換相時可能引起的功率變換器飽和現(xiàn)象。
