Abstract: The present invention provides coordinated control methods of generator and SVC for improving power plant active power throughput and controller thereof. The method comprises: measuring the required input parameters for the generator and SVC control; judging the system topology and the control mode of SVC to determine the operation mode; and calculating the control reference based on the operation mode to control the generator and/or SVC. The proposed methods and coordinated controllers enable the SVC to share the required reactive power output of the power plant, convert the generator into “unity-power-factor-generator”, and therefore extend the active power output capability of the power plant.

Abstract: The present application discloses a method to optimize operation of a transformer cooling system, the corresponding cooling system, and a method to determine the capacity of Variable Frequency Drives (VFD) that are used in the transformer cooling system. The method comprises: preprocessing the initial data input by user; collecting the on-line data, and calculating the optimized control command to meet the requirement of the transformer loss, top-oll temperature variation and noise; and executing the control actions by controlling a controllable switch and/or sending a control command to a VFD. Compared with the existing prior arts, the proposed solutions are much more intuitive and practical in the field of the cooling system.
