| 摘 要： | 直流潮流算法在电力系统中应用广泛,但目前的直流潮流算法大多无法准确计算节点电压幅值和支路无功潮流。因此,文中基于经典直流潮流算法,考虑无功功率方程,提出了一种计及电压与无功功率的直流潮流算法,可在保留直流潮流算法线性与快速性的前提下,实现节点电压幅值与无功潮流的近似求解。对IEEE 118节点系统、Polish 3012节点系统和国内实际大系统的仿真验证表明,所提出的改进直流潮算法能够精确、快速地求解系统中的节点电压幅值与无功潮流。

| Abstract: | DC power flow calculation methods are widely used in the power system. However, those methods are still incapable of calculating voltage amplitudes and reactive power flows accurately. Based on the standard DC power flow calculation method and the complex reactive power equation, this paper proposes a novel DC power flow calculation method considering voltage and reactive power. On the premise of reserving the linear properties and quickness of DC power flow calculation method, the bus voltage amplitude can be approximately solved. The simulation results in IEEE 118-bus system, Polish 3012-bus system and a real power system in China show that the proposed method is able to accurately and efficiently solve the voltage amplitude and reactive power flow.
