Transmission network

This paper studies on establishing the mathematical optimization formulation to coordinate the operating times of directional overcurrent relays in transmission networks. The objective function of this optimization formulation is to minimize the total operation time of all directional overcurrent relays, and it must satisfy the highly nonlinear constraints such as the time multiplier setting range, the plug setting range, and the coordination time interval between the primary and backup relay pair.

The application of hydro-mechanical transmissions is recently the trend in agricultural vehicles where a continuously variable transmission ratio has advantages. Hydro-mechanical transmissions provide efficient power transfer while maneuverability is still maintained, and therefore, fuel efficiency is enhanced.

A bit (binary digit) is the smallest unit of information • N = 2n where N is the number of representations and n is the number of bits (ex. ASCII, Unicode, PCM code etc.) • Data communications transfer information using codes that are transmitted as signals (either analog or digital) • In general, analog lines provide a slow service that contains high error rates.

Carrier Sense Multiple Access (CSMA) is a probabilisticMedia Access Control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium CAN uses a nondestructive bitwise arbitration, which means that messages remain intact after arbitration is completed even if collisions are detected. All the arbitration takes place without corruption or delay of the message that wins the arbitration.
