Patent ID: 8527222

Claim:
A method for determining installation locations of a plurality of fault indicators in a power network, with the method comprising: a database retrieving step including using a processor to retrieve a power network in a database; an installation location setting step including using the processor to set a predetermined number of installation locations of the fault indicators, with the installation locations of the fault indicators being on predetermined locations of the power network, with a detection zone formed between two adjacent installation locations of the fault indicators; a fault analyzing step including using a fault analyzing module to generate a plurality of fault points in the detection zones based on fault ratio information of each of the detection zones stored in the database, with a number of the plurality of fault points in each of the detection zones being in proportion to a fault ratio in the detection zone, with locations of the plurality of fault points in each of the detection zones being recorded in one of the installation locations of the fault indicators in the detection zone; a communication quality analyzing step including using a communication analyzing module to measure a communication quality of each of the detection zones to create a communication quality information cumulative probability, and using a random analysis method to calculate a successful communication probability of each of the detection zones; a successful probability determination step including using the processor to determine whether the successful communication probability in each of the detection zones is larger than a communication standard, and completing determination of the installation locations of the fault indicators in the power network if the successful communication probability in each of the detection zones is larger than the communication standard, or carrying out an installation location updating step if the successful communication probability in any of the detection zones is not larger than the communication standard, with the installation location updating step including using the processor to retrieve the detection zones having a successful communication probability smaller than the communication standard, moving any one of the installation locations of the fault indicators through a unit distance towards a center of the corresponding detection zone having the successful communication probability smaller than the communication standard, and carrying out the fault analyzing step again.
