Title:
ACQUISITION METHOD FOR MINIMUM PHASE LINEAR ACTIVE POWER FLOW OF AC POWER NETWORK
Document Type and Number:
WIPO Patent Application WO/2016/061745
Kind Code:
A1
Abstract:
An acquisition method for a minimum phase linear active power flow of an AC power network. The method includes: according to known AC power network parameters, known AC power network running characteristics and known node injection active power, establishing a symmetric linear function relationship of the node injection active power with respect to a node voltage phase; according to the symmetric linear function relationship, establishing a minimum phase linear function relationship of the node voltage phase with respect to the node injection active power, and acquiring a minimum voltage phase of each node in the AC power network; and according to the minimum phase linear function relationship, a known branch non-linear active power flow, the known node injection active power and the known AC power network running characteristics, establishing a linear function relationship of a branch minimum phase linear active power flow with respect to the node injection active power, and acquiring a minimum phase linear active power flow of each branch. An acquisition result of the acquisition method is unique, follows a circuit law, and can accurately reflect substantive characteristics of a phase state variation of the AC power network.
