礦井提升機供電系統電能質量治理研究

林振烈+肖津+唐朝暉

【摘要】諧波和無功是影響提升機供電系統電能質量的兩大因素，提升機是礦山主要的耗能設備，由于負載與流裝置會產生諧波和無功，為解決諧波以及無功功率給電網其他用電設備以及周圍用戶所帶來的電能質量問題，結合提升機負載特性，提出了一種由靜止同步補償器SVG（Static Var Generator）+ FC（Fixed Capacitor）組成的諧波治理和無功補償方案。文中介紹了SVG補償原理和容量計算方法，并且闡述了FC濾波支路的設計原理與參數設計方法，通過分析SVG的優勢及其電能質量治理效果，證明SVG+FC聯合治理方案是有效的。

【Abstract】The harmonic and reactive power are two factors which affect the power quality of the Mine Hoist power system. Hoist is the main energy-consuming equipment of mines. As the load rectification equipment can produce reactive power and harmonic. In order to solve the power quality problem which is brought by harmonic and reactive power，and that effect other electric equipment and users. According to Hoists load characteristic, the paper proposed a harmonic suppression and reactive compensation scheme which is made up of SVG (Static Var Generator) and FC (Fixed Capacitor) .The paper has also introduced the compensation principle and capacity computing method of SVG. Whats more, this article has elaborated design principle and parameters setting method of FC filter branch. By analysis the advantages of SVG and the governance effect to power quality after implementing join compensation scheme. The result has proved that the SVG+FC join compensation scheme is effective.
