Embodiment Construction

[0041] The present invention will be further described in detail below with reference to the accompanying drawings.

[0042] like figure 1 , The present invention provides a rotary flow control and coordination UHV series compensation configuration, the following steps:

[0043] Step 1, to determine the target coordinates configuration;

[0044] Determining the target coordinates configuration, the objective function is formed RPFC and series compensation for synergies. In most cases to channel transmission capacity as the objective function, taking into account the flexibility to control demand.

[0045] Step 2, and series compensation RPFC determines the installation position;

[0046] For a given transmission channel, the RPFC with series compensation may be installed in the same line, the line may be mounted in parallel, respectively. The former requires RPFC and series compensation in order to achieve synergy where both lines maximum transmission capacity, choose the line whe...

Abstract

The present invention provides a method for coordinating configuration of a rotating power flow controller and UHV series compensation. The method includes the following steps: (1) determining a coordinated configuration target; (2) determining the installation position of the rotating power flow controller and UHV series compensation; (3) Develop a preliminary screening scheme for the parameters of the rotating power flow controller and UHV series compensation parameters; (4) Adjust the control parameters of the rotating power flow controller, and verify the flexible control range of the rotating power flow controller; (5) Propose the rotating power flow control The optimal configuration scheme for the coordination of the converter and the UHV series compensation. The invention solves the coordination configuration problem of the RPFC parameters and the serial compensation parameters of the AC outgoing channel of the large-scale energy base.

Description

Technical field [0001] The present invention belongs to the field of power system planning, particularly relates to a rotary flow control and coordination UHV series compensation configuration. Background technique [0002] 1990s, American GE Company proposed a phase transformer (rotary phase shifting transformer, referred Spray Rapid Tooling) based on a conventional rotary transformer and a shift FACTS device, i.e., the rotational power flow controller (rotary power flow controller, referred RPFC). In 2000, GE company in Japan Sunan 500kV middle of the grid substation put into operation a set RPFC, the trend for the balance between the number of loops. RPFC core component is RPST, making it insufficient Unified Power Flow Controller (UPFC) in the regulation of speed, but have control RPFC simple, strong ability to withstand shocks, low loss and low cost characteristics, value and has broad application space . [0003] Application of series compensation technology began in 1928 (...
