Real-time control device and method for distributed power reactive power optimization

Abstract

The invention discloses a real-time control method for reactive power optimization of distributed electric power. The method includes: collecting real-time data reflecting the operating state of the power system; Performing reactive power optimization calculations on the real-time data to obtain optimized output control quantities; and transmitting the optimized output control quantities to reactive power adjustment actuators through the mobile Internet, so as to distribute the power system Real-time control of reactive power optimization. The invention realizes the application of the public Internet, especially the public mobile Internet technology, to the distributed real-time control of power system reactive power optimization, and based on the modeling method of the new networked control theory, the state estimation is adopted in the feedback loop, and the The de-redundancy-holding process is carried out in the forward channel, which well overcomes the adverse effect on the real-time control of reactive power optimization due to data packet loss in the public communication network.

Description

technical field [0001] The invention relates to reactive power optimization control of electric power system, in particular to real-time control equipment and method for distributed power reactive power optimization. Background technique [0002] At present, the power system generally transmits the collected real-time data through a dedicated communication network, so as to perform distributed reactive power optimization control. The laying and maintenance costs of this type of dedicated communication network are very high, and when the original dedicated communication line is damaged, multiple redundant paths cannot be provided for use. However, the current public Internet has been widely used in both wired and wireless forms, and relatively cheap solutions can be obtained. However, when this kind of public network is used to solve data transmission such as real-time control of power system reactive power optimization, data packet loss will occur when the network is busy, ...
