Patent ID: 7899582

Claim:
A method for calculating availability for a line power system, the method comprising: determining a loop length required for the line power system having at least one power circuit unit interconnecting at least first and second locations; determining a number of first and second location circuits for the line power system; calculating a number of line power system circuits based on the loop length and the number of first and second location circuits; calculating a total power delivered over the line power system; calculating, using a processor, at least one location circuit availability measure based on the loop length, the number of first and second location circuits, the number of line power system circuits, the total power delivered, and at least one parameter representing at least one of a second location, an environmental variable, and a failure or repair statistic associated with the line power system; calculating, using the processor, a line power system availability measure based on the loop length, the number of first and second location circuits, the required number of line power system circuits, the total power delivered, and at least one parameter representing second locations or repair time statistics associated with the line power system; and generating a calculated line power system availability plot.
