Embodiment Construction
[0044] The present invention will be described in detail below in conjunction with the accompanying drawings. Such as figure 1 Shown is a flowchart of a comprehensive evaluation method for the severity of voltage sags in a specific embodiment of the present invention, including the following steps:
[0045] Step 1. Establish attribute sets and scheme sets;
[0046] Step 2. Determine the combination weight of each index in the attribute set based on the entropy weight method and the variation coefficient method;
[0047] Step 3. Comprehensive evaluation of voltage sag based on weighted ideal point method;
[0048] Through the comprehensive evaluation method of voltage sag severity in the present invention, the severity of a voltage sag event at a certain node can be accurately and conveniently and effectively evaluated, so as to facilitate voltage sag control and economic compensation calculation.
[0049] In a specific embodiment, in step 1 of the method for comprehensively...
