An advanced concept in electrical power distribution control and management

This paper presents a new concept in electrical power distribution systems for air craft and compares the conventional approach to this concept. The historical development of this concept is presented and system application as developed by the Air Force and Navy laboratories is discussed. Some of the capabilities of an electrical system using this concept are presented. Electrical distribution systems perform four basic functions. These are: (a) to gather control data information, (b) to determine from this data the proper control action, (c) to transmit this control information to the location of the control action, and (d) to perform the necessary control action. The electrical distribution system must do the above four items in a safe and orderly manner which will not result in fire or other unsafe conditions if a short circuit or any other malfunction occurs. Thus, i t must also provide circuit protection and failsafe operation.
