摘要 系統(tǒng)無功分布的合理與否直接影響著電力系統(tǒng)的安全與穩(wěn)定,并與經(jīng)濟效益直接掛鉤。無功優(yōu)化控制是保證電力系統(tǒng)安全、經(jīng)濟運行的一項有效手段,是降低網(wǎng)絡有功網(wǎng)損,提高電壓質量的重要措施。因此電力系統(tǒng)無功優(yōu)化問題的研究既具有理論意義,又具有實際應用價值。 通過大量閱讀各類文獻后,了解到安裝了配電網(wǎng)無功補償裝置以后,可以提供感性負載所消耗的無功功率,減少了電網(wǎng)電源向感性負荷提供線路輸送的無功功率,減少了無功功率在電網(wǎng)中的流動。配電網(wǎng)無功優(yōu)化可有效地降低線路輸送無功功率所造成的電能損耗,提高系統(tǒng)的電壓合格率,降低網(wǎng)絡運行費用,提高供電質量。 本文主要研究了10kV 配電網(wǎng)無功補償裝置的合理配置。介紹了無功補償?shù)幕靖拍?,補償方式以及電壓和補償功率的關系,補償?shù)娜萘亢臀恢玫膬?yōu)化等。通過無功優(yōu)化算法,在提高功率因數(shù)的前提下,可以比較簡便的計算出在單電源配電網(wǎng)中最佳無功補償容量。最后采用簡單數(shù)據(jù),對三種方法進行無功容量的實例計算,確定無功容量,分析其經(jīng)濟效益,并用條形圖進行比較分析。 關鍵詞:配電網(wǎng),無功優(yōu)化,無功補償容量
Abstract The reasonable or not in the distribution of reactive power systems is affect the security and stability of the power system directly, and linked to economic benefits directly .Reactive power optimization control is an effective means to ensure the power system security, and economic operation, an important measure to reduce the network of active power loss and improve voltage quality. The problem of reactive power optimization has both theoretical significance, but also has practical value. By a lot of reading all kinds of literature, I learned that Distribution network is installed after the reactive power compensation device to provide inductive load reactive power consumption, reducing the grid to provide power to the inductive load reactive power transmission lines, reducing the reactive power flow in the grid. Optimization of Reactive Power transmission lines can effectively reduce the reactive power caused by the energy loss and improve the system voltage pass rate, reducing network operating costs, improve quality of power supply. Introduces the basic concepts of reactive power compensation, compensation mode and the relationship between voltage and reactive compensate for the power, the capacity of the compensation and position optimization. Through the reactive power optimization algorithm, the premise of improving the power factor can be calculated relatively simple single-supply distribution network in the best reactive power compensation capacity.Finally, use a simple data, the reactive capacity of the calculation, the reactive capacity of the calculation, and three ways to determine the reactive capacity, to analyze the economic benefits, and a comparative analysis of a bar graph. Key words: Multivariable system, Predictive control, Reactive compensation capacity
