查询词典 Var

In high-voltage var compensation field, when switching the capacitor banks by mechanical switch, it is easy to bound when it closes and to restrike when it opens, and the mechanical switch can not be switched frequently. When switching the capacitor banks by electronic switch in series, it needs dynamic and static voltage sharing circuit and synchronous triggering circuit. It leads to complex structure and high cost.

为解决当前高压无功补偿领域采用常规机械开关投切电容器组开关合闸时触点弹跳产生过电压，分闸时易重燃及不可频繁操作，而采用串联固态电子开关需要相应的动、静态均压及同步触发电路导致系统结构复杂且成本较高的问题，提出一种基于新型高压投切开关的高压动态无功补偿装置。

Five ways on comparing covariance matrix are applied to the Shanghai 50 Indexes Stock Exchange, which are sample covariance matrix, scalar matrix, two-parameter covariance matrix, single index matrix, constant correlation matrix. We adopt principal components method and Markowitz portfolio method to measure stock market risk using VaR, getting the effect of measuring market risk. The result shows that sample covariance matrix and two-parameter covariance matrix could measure market risk more effectively.
