The invention provides a power distribution area unbalance control measure determining method, a power distribution area unbalance control measure determining device, and equipment. A current-related coefficient of every three-phase current reasonable data group is calculated, and thereafter an A phase-B phase current-related coefficient, a B phase-C phase current-related coefficient, and a C phase-A phase current-related coefficient of every current-related coefficient are compared with a first correlation threshold value, and whether consistency between the changing trends of at least two of three phases of current in a target power distribution area exists is determined, and then a first number, a second number, and a third number are respectively compared with a first verification numerical value. When any of following conditions that the first number is greater than or equal to the first verification numerical value, the second number is greater than or equal to the first verification numerical value, the third number is greater than or equal to the first verification numerical value is true, an artificial phase modulation result is generated, and therefore on a basis of improvement of precision, a matching degree between the power distribution area and the artificial phase modulation measure is improved, and costs required by a control process are reduced.
