Abstract

There is described a refrigeration system 10, the refrigeration system 10 comprising an induction motor 18 having a rotor 23, wherein the refrigeration system 10 is configured to: supply 102 an alternating current to the induction motor 18 to induce rotation of the rotor 23, wherein rotation of the rotor 23 powers one or more loads 20, 21 of the refrigeration system 10; identify 104 a predetermined threshold value R_t1 of a parameter R of the induction motor 18 and a predetermined relationship associated with the induction motor 18 between the parameter R and a derating amount P₁, the parameter R being an angular velocity or a slip of the rotor 23 of the induction motor 18; determine 106 the parameter R of the rotor 23 during rotation of the rotor 23; determine 108 whether the determined parameter R meets a first condition, the first condition being the angular velocity R being less than the predetermined threshold value R_t1 or the slip being greater than the predetermined threshold value R_t1; upon determining that the first condition has been met, determine 110 a derating amount P₁ based on the determined parameter R and the predetermined relationship; and derate 112 the one or more loads 20, 21 by the derating amount P₁. There is also described a method 100, 200, 300, 400, 500 of operating a refrigeration system.
