With the traffic lights control as an example, this paper proposes the application of contact compare instruction and transfer instruction to program design method, making the program structure compact and statement concise. The control requirements are easily completed. Key words: Function Instruction; Programming; Traffic Lights; Contact Compare Instruction; Transfer展开更多

The paper summarizes the application, including system aspects that require special control functions in the SVC (static var compensator) regulator. Several important benefits for the system operation are demonstrated, such as increased power transmission import over an existing 230 kV network, dynamic bus voltage stabilization for various load conditions, including system outages and load rejection, and reduction of variable speed drive shutdowns by up to 95%. Some relevant design features of the SVC are treated, as well.展开更多
