Firstly, total system differential equations and algebraic equations are used to form the linearization expressions under steady state conditions. The distribution property of generators in initial operating state is determined under system multi-operation conditions. 先利用全系统微分方程和代数方程,在稳态条件下形成系统化的线性化解析表达,确定多运行方式下的发电机初始运行状态的分布特性。
