有效、准确的潮流算法为有功调度和初始稳态运行点提供控制参考，用于稳定分析、短路计算和电磁暂态仿真，不仅是分析系统运行工况的基本前提，也是提高基于多端电压源换流器的高压直流输电（VSC-HVDC）潮流和直流电压控制精度的基础。针对新开发的双极型多端电压源型直流输电系统（VSC-MTDC），提出了一种基于节点电压的通用稳态潮流算法。首先，针对双极型VSC-MTDC的正负极直流网络可以独立运行的特点，提出了一种双极潮流交替迭代法求解正、负极直流网络潮流。其次，针对通用潮流算法，提出了一系列包含多种控制策略的节点等值方法。给出了通用潮流算法的详细计算过程和通用MATLAB（TM）程序。在PSCAD/EMTDC中建立了一个典型的四端双极型电压源型MTDC系统，验证了该算法的有效性，并对结果进行了讨论。此外，更复杂的双极VSC-MTDC系统在不同的操作条件下，采用所提出的通用潮流算法的计算结果，以说明其通用性和有效性。
An effective and accurate power flow algorithm provides control references for active power dispatch and initial steady state operating points, used for stability analysis, short-circuit calculations, and electromagnetic transient simulations, which is not only a fundamental precondition to analyze the system operating conditions, but also the basis to improve the accuracy of power flow and DC voltage control of the multi-terminal voltage source converter-based high voltage direct current (VSC-HVDC). This paper proposes a nodal voltage-based universal steady-state power flow algorithm for the newly-developed bipolar multi-terminal VSC-HVDC (VSC-MTDC). Firstly, as the positive-pole and negative-pole DC network of the bipolar VSC-MTDC can be operated individually, a bipolar power flow alternating iterative method is proposed here to obtain the positive/negative-pole DC network power flow. Secondly, a series of nodal equivalent methods involving various control strategies are proposed for the universal power flow algorithm. Then the detailed calculation procedure and a general MATLAB(TM) program for the universal power flow algorithm is presented. A typical 4-terminal bipolar VSC-MTDC system was built in the PSCAD/EMTDC to verify the validity of the proposed algorithm, and the results are discussed here. Moreover, the calculation results of more complex bipolar VSC-MTDC systems under different operating conditions, employing the proposed universal power flow algorithm, are presented to illustrate its universality and efficiency.
