METHOD FOR OBTAINING A SYMMETRICAL POWER TRANSMISSION COEFFICIENT WHEN POWER SUPPLY POWER AND LOADS POWER CHANGE AT THE SAME TIME IN THE ALTERNATING CURRENT POWER NETWORK

Document Type and Number:

WIPO Patent Application WO/2016/077994

Kind Code:

A1

Abstract:

A method for obtaining a symmetrical power transmission coefficient when power supply power and loads power change at the same time in the alternating current power network belongs to the field of electrical engineering. The method comprises: establishing a linear function relationship of transmission power on branches with power consumption related to the node voltage phase according to a non-linear function of transmission power on branches and parameters and operating characteristics of the alternating current power network; then establishing a symmetrical linear function relationship of node power of power supply and loads related to the node voltage phase in combination with the node power of power supply and loads and according to this establishing a symmetrical linear function relationship of the node voltage phase related to the node power of power supply and loads; next, obtaining a symmetrical power transmission coefficient from the node power of power supply and loads to the transmission power on branches with power consumption when the node power of power supply and loads change at the same time in combination with the linear function relationship. The obtained result is unique, follows circuit rules, adapts to the fact that the node power of power supply and loads change at the same time and there is consumption in the alternating power network and truly reflects the essential characteristics of power transmission from the node power to the transmission power on branches.
