A supervision control system and its operational principle for leading phase operation of multi-generators are presented in this paper. The principle of leading phase operation of generator is discussed firstly. Then the software of LabVIEW is introduced briefly. The application of fractional order controller for the supervision control system of leading phase operation of multi-generators is given. The system is comprises of Beidou satellite system module, power angle measurement and calculation module, parameter identification module, interface conversion module, display module, etc. The clock signal of the system is generated by Beidou satellite navigation system. Then, the design of supervision control system based on LabVIEW is given. Based on the LabVIEW platform, the running state and convenient management of leading phase operation of multi-generators are achieved. If a generator exceeds the limit value, the reactive power is adjusted immediately by the corresponding monitoring unit, until the appropriate range is obtained. The supervision control system is safe and reliable, and with relatively high precision.
