摘要:

本文讨论了高压直流输电系统的一级控制问题,提出了四个主要贡献:首先,提出了一种新的非线性模型,考虑了传统内控制器引入的非线性特性;其次,确定了平衡点存在的必要条件,这些条件依赖于某些自由控制器调参参数;第三,制定了额外的条件以确保平衡点满足功率分配约束;第四,建立了给定平衡点稳定性的条件。通过四端口示例的数值计算验证了理论结果的实用性。

英文摘要:

The problem of primary control of high-voltage direct current transmission systems is addressed in this paper, which contains four main contributions. First, to propose a new nonlinear, more realistic, model for the system suitable for primary control design, which takes into account nonlinearities introduced by conventional inner controllers. Second, to determine necessary conditions - dependent on some free controller tuning parameters - for the existence of equilibria. Third, to formulate additional (necessary) conditions for these equilibria to satisfy the power sharing constraints. Fourth, to establish conditions for stability of a given equilibrium point. The usefulness of the theoretical results is illustrated via numerical calculations on a four-terminal example.
