Embodiment

[0034] The invention relates to a capacity matching and grading method of a capacitor bank and a static var compensator, a reactive power compensation device for a power distribution network integrated with a capacitor bank and a static var compensator, and a coordination controller. The present invention is described in detail respectively starting from several key links such as the capacity planning and design of the reactive power compensation device, the realization of the reactive power compensation device, and the coordinated control.

[0035] Such as figure 1As shown, this embodiment includes several parts such as a large group of capacitors, a small group of capacitors, a static var compensator (SVC) and a coordinated controller. Both the large group capacitor and the small group capacitor are connected to the substation bus or line through switching switches, and the static var compensator (SVC) is directly connected to the substation bus or line. On the one hand, th...

Abstract

The invention relates to a capacitor bank and SVC (static var compensator) cooperated integration power distribution network reactive compensation device, which comprises several parts such as a capacitor bank and SVC capacity matching and grading method, a capacitor bank and SVC cooperated integration power distribution network reactive compensation device and a coordination controller, wherein the capacitor bank and SVC cooperated integration power distribution network reactive compensation device comprises three parts including a large-bank capacitor, a small-bank capacitor and a SVC. Firstly, starting from the planning and design angle, the capacity of the capacitor bank and the SVC is determined according to the capacitor bank and SVC capacity matching and grading method; the coordination controller performs analysis according to the collected real-time data and the switching number limitation of the capacitor bank, makes the switching decision of the capacitor bank and coordinates the action of the SVC. Compared with the prior art, the power distribution network reactive compensation device has high cost performance.

Description

technical field [0001] The invention relates to a distribution network control technology, in particular to a reactive power compensation device for a distribution network in which a capacitor bank and a static var compensator (SVC) are cooperatively integrated. Background technique [0002] During the operation of the distribution network, more and more attention has been paid to the problem of reactive power planning. A reasonable reactive power compensation method and planning is a major means to improve the power quality and operation economy of the distribution network. Since the distribution network directly faces users and has a very wide distribution, especially the 10kV and 380V distribution network, the number of substations and the length of the line (km) are very large. Therefore, the number of reactive power compensation devices required is also very large. [0003] It is precisely because the number of reactive power compensation devices required by the distri...
