摘要
并联电容器在电网运行中产生大量谐波,由于相互作用会产生谐波放大甚至将会出现并联谐振,严重影响电能质量,危及电网的安全经济运行。通过分析并联补偿电容器与系统谐波放大的原理,说明了其对电网造成的危害,并提出抑制谐波放大的实施对策。
Shunt capacitors generate a large number of harmonics in the power grid operation. Because of the interaction harmonic will be enlarged or even parallel resonance will be appeared. This will seriously affect the power quality, and endanger the safety operation of power grid. Through analyzing the theories of shunt compensation capacitor and system harmonic enlargement, the danger to the power grid is shown, and the countermeasures to suppress the harmonic enlargement are put forward.
