矿井提升机供电系统电能质量治理研究

林振烈+肖津+唐朝晖

【摘要】谐波和无功是影响提升机供电系统电能质量的两大因素，提升机是矿山主要的耗能设备，由于负载与流装置会产生谐波和无功，为解决谐波以及无功功率给电网其他用电设备以及周围用户所带来的电能质量问题，结合提升机负载特性，提出了一种由静止同步补偿器SVG（Static Var Generator）+ FC（Fixed Capacitor）组成的谐波治理和无功补偿方案。文中介绍了SVG补偿原理和容量计算方法，并且阐述了FC滤波支路的设计原理与参数设计方法，通过分析SVG的优势及其电能质量治理效果，证明SVG+FC联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.
