The invention discloses an energy-saving management platform based on whole network monitoring reactive compensation technology. The energy-saving management platform comprises a master control program module, a database module and an SCADA system interface module. The SCADA system interface module is used for allowing a reactive voltage optimization server to collect state parameters of the head end of a 10kV distribution network from an SCADA system of a dispatching center; and the master control program module is used for allowing a master control program to obtain such data from a memory database of the database module, then, carrying out a series of calculating and processing to generate comprehensive instructions for adjusting capacitors and taps, and sending control information to each controller to execute operation. The management platform realizes display of data information, such as node voltages, transformer current, capacitor compensation capacity, bus switch state and power factor, which are controlled by different controllers, in a display device, and realizes remote control of behaviors of each controller; and in the analysis process, the system can keep records of the whole process according to actual needs, thereby providing data basis for follow-up analysis.
