Abstract

Circuit component connectivity evaluation and validation method provides comparing and validating the correctness of electrical phase connectivity at connection nodes between conducting components within a circuit model of a power distribution network or other circuit. Phase connectivity requirements of each connected component/device/equipment in a particular circuit are obtained from a Common Interface Model (CIM) file containing parameter data describing the circuit. XML data strings obtained from the CIM file are parsed into enumerated data objects representing each component'"'"'s phase connectivity requirements and assigned unique four bit binary phase connectivity mask values indicative of the particular electrical phase connectivity requirements of each component. Associated mask values corresponding to connection nodes between pairs of connected components are bit-wise logically “AND”ed and the result compared to each component'"'"'s bit mask to validate that each connected component in the circuit is a correct phase type match with other components to which it is connected.

1. A method, implemented by a computer system having one or more processors and used for circuit model management/exchange between entities communicating over a network, for comparing and validating a phase connectivity of connected conducting electrical components in a circuit model, the method comprising:

assigning a unique binary phase-type connectivity mask value to each of possible different phase connection types associated with conducting electrical components in a particular circuit or circuit portion;

obtaining phase connectivity attribute data for a plurality of components of the circuit or circuit portion;

assigning a corresponding phase-type connectivity mask value indicative of the electrical phase connectivity requirement for a first component based on obtained phase connectivity attribute data for said first circuit component;

assigning a corresponding phase-type connectivity mask value indicative of the electrical phase connectivity requirement for a second component based on obtained phase connectivity attribute data for said second circuit component;

evaluating and validating pairs of connected components in the circuit, using said one or more processors, by;

i) performing a bit-wise logical ‘

AND’

operation between assigned phase-type mask values of said first and second circuit components;

ii) comparing a result of the logical ‘

AND’

operation with each individual assigned phase-type mask value of both said first and second circuit components, wherein

if either comparison results in a match, the phase connectivity between said first and said second component is validated and the first and the second component are identified as being electrically connectable;

or conversely,

if neither comparison results in a match, the phase connectivity between said first and said second component is not validated and the first and the second component are considered as not being electrically connectable;

repeating operations (i) and (ii) above until all connections between connected components in the circuit model have been evaluated; and

communicating said component validation results of an evaluated circuit model to one or more entities in said communications network.

8. A non-transitory computer-readable tangible storage medium embodying one or more sequences of computer-executable processing instructions which, when executed by one or more computer processors of a MEP/model manager system in an information exchange/communications network, causes the system to perform operations and/or functions of evaluating and validating phase connectivity for electrical components of a circuit model provided in a data file, the processing instructions comprising:
