基于eCOG1k自准同期并网装置的频率和相位角测算的研究

The research of the incorporation installment frequency and phase synchronal surveyed based on eCOG1k

在电力系统中，发电机的并网操作是电厂的一项重要操作。在并网条件允许的条件下，自准周期并网装置在合闸导前时间到来时，发出并网指令，使电机组平稳的并入系统电网中，采用eCOG1k单片机完全可以满足并网装置控制的要求，并快速、可靠的获取所需要的参数信息。经过实验，这些方法是切实可行的。

Network-joining is one of the important manipulation procedures in power plants. In the condition of the incorporation installment allowed, when the advanced insertion time of closing resistor is coming, gives the command, lets the power grid merge into the power system smoothly. With the eCOG1 k singlechip it completely meets demand of the incorporation installment, gained the parameter information fastly and reliably. The experiment proved this method was practical feasible.
