采用净现值法的电能质量综合补偿装置不同控制策略下的经济性评估

Economic Evaluation of Power Quality Comprehensive Compensation Device Using Net Present Value Method Under Different Control Strategies

有源与无源并联运行的电能质量综合补偿装置结合了传统有源与无源补偿装置的优点,在低压配电台区应用前景广阔。本文基于配电台区的实测数据,分析了配电台区电能质量综合补偿装置的典型运行工况。针对不同运行工况,采用净现值法对补偿装置传统控制方法进行经济性评估。通过对评估结果进行分析,提出一种净现值最优的配电台区电能质量综合补偿装置控制方法,并进行仿真验证和实例计算,结果表明,该控制方法在不同工况下均能实现净现值更优,更适合在配电台区电能质量综合控制装置应用。

The power quality comprehensive compensation device with active and reactive parallel operation combines the advantage of traditional active and reactive compensation device and finds wide application prospects in low voltage distribution area.In this paper,the typical operation condition of power quality comprehensive compensation device in the distribution area is analyzed on the basis of actually measured data of the distribution area.For the different operation conditions,the economic evaluation for the traditional control method of the compensation device is performed by the net present value method.Analysis is made through the evaluation result and the control method of power quality comprehensive compensation device of the distribution area with a kind of optimal net present value,the simulation verification and example calculation are made.It is shown by the result that the control method can achieve optimal net present value at different conditions and is more suitable for application in the power quality comprehensive control device in the distribution area.
