查询词典 random function

For the principal component, namely the voltage stability analysis function, three kinds of nodal injection power modes are defined, i.e., the random varying direction of load, the response setting direction of generator and the ratio of active power component to reactive power component in load power, and a continuous power flow model that is easy to utilize and comprehend by dispatching center is built, based on this model three kinds of formulae to calculate the sensitivities of loading margin with respect to three kinds of nodal injection power modes are derived respectively, and on this basis the influence of nodal injection power mode on loading margin can be analyzed in order that the voltage collapse can be avoided by fast implementing early warning of voltage stability and adopting effective corrective control.

文章针对N-EMS的主要组成部分--电压稳定分析功能，定义了3类节点注入功率模式：负荷的随机变化方向、发电机的响应设定方向、负荷的有功和无功比例，建立了易于被调度中心运用和理解的连续潮流模型，在此模型基础上分别推导得到负荷裕度对3类模式的灵敏度公式，据此分析节点注入功率模式对负荷裕度的影响，以便能够快速进行电压稳定预警和采取有效的校正控制来避免电压崩溃。

The paper to analyzes because experiments "factor contribution rate".to conduct the research;Discovered "the pure factor from difference square" for the negative value is the statistic stochastic value result;When the factor function is not extremely remarkable,the factor contribution rate also is a negative value;By now should merge not the remarkable factor square the random error square,recomputation ANOVA as well as factor technical progress factor.

论文对析因试验中用于分析因子作用的"因子贡献率"进行研究；发现"纯因子离差平方和"为负值其实是统计量随机取值的必然结果；尤其当因子作用极不显著时，计算的因子贡献率常常也是负值；这时应该将不显著的因子平方和并入随机误差平方和，重新进行ANOVA以及计算因子贡献率。
