Embodiment Construction

[0040]The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] figure 1 A high-voltage and large-capacity STATCOM state assessment method is shown, including:

[0042] S1. Establish a first-level evaluation model and a second-level evaluation model, and group STATCOM equipment according to the basic characteristics of different equipment;

[0043] S2. According to the first-level evaluation model, the status information of each grouping equipment is initially collected as the first-level evaluation index, and the first-level evaluation calculation is performed on each grouping device in turn to obtain the failure rate of each grouping device; the status information of each grouping includes preventive test data , real-time ope...

Abstract

The invention provides a state evaluation method and system for a high-voltage large-capacity STATCOM (Static Synchronous Compensator). The method includes S1, establishing a first-level evaluation model and a second-level evaluation model and grouping devices of the STATCOM according to basic characteristics of the different devices; S2, according to the first-level evaluation model, collecting state information of the different grouped devices preliminarily as first-level evaluation indexes for performing first-level evaluation calculation on the grouped devices successively and obtaining the failure rates of the grouped devices; S3, if whether the grouped devices meet failure or not cannot be judged accurately according to the failure rates, further collecting the state information of the grouped devices as second-level evaluation indexes for calculation according to the second-level evaluation model, and determining the failure devices and reasons. According to the invention, through establishing the evaluation models of the two levels and selecting partial indexes in each model of each evaluation model for calculation and analysis, the evaluation process is simplified and resource waste is avoided.

Description

technical field [0001] The present invention relates to the technical field of electronic power equipment performance detection, and more specifically, to a high-voltage and large-capacity STATCOM state evaluation method and system. Background technique [0002] Static Synchronous Compensator (STATCOM) is a parallel reactive power compensation flexible AC transmission (Flexible Alternative Current Transmission Systems, FACTS) device, which can emit or absorb reactive power, and its output can be changed to control Specific parameters in power systems. As an advanced reactive power compensation device, it can simultaneously solve the problems of reactive power, harmonics and three-phase unbalance in power quality. The main equipment included in the ultra-large-capacity STATCOM includes high-voltage and large-capacity transformers, reactors, high-voltage switches, IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor) power units, water cooling systems, e...
