Description

基于无线传感技术的有源滤波装置
技术领域
本实用新型涉及一种有源滤波装置，尤其是涉及一种基于无线传感技术的有源滤波装置。
背景技术
有源滤波装置的应用可克服LC滤波器等传统的谐波抑制和无功补偿方法的缺点(传统的只能固定补偿)，实现了动态跟踪补偿，而且可以既补谐波又补无功。有源滤波装置在使用时需要有一组采样信号的输入(互感器)，以此信号来分析被测电流的谐波从而控制逆变器输出相反等量的谐波将其抵消补偿。在实际应用中采样信号的质量决定了补偿效果，和设备的稳定程度，在很多现场采样源(互感器安装的位置)到滤波器距离非常的长(30米以上)，同时很多有与电力线缆产生干涉的机会，所以最终获得的采样信号失真度高。
发明内容
本实用新型的目的就是为了克服上述现有技术存在的缺陷而提供一种传输干扰低、传输距离长的基于无线传感技术的有源滤波装置。
本实用新型的目的可以通过以下技术方案来实现：
一种基于无线传感技术的有源滤波装置，包括互感器、数字信号处理器和逆变器，所述的逆变器与数字信号处理器连接，所述的互感器上安装有无线传感采样转换器，所述的数字信号处理器上连接有无线接收器，所述的无线传感采样转换器包括相连接的内置采集转换电路和无线发送电路，所述的无线发送电路通过无线网络与无线接收器连接。
所述的无线发送电路上连接有发送天线。
所述的无线接收器上连接有接收天线。
所述的无线网络包括WiFi、GPRS或ZigBee。
与现有技术相比，本实用新型在采样部分使用了无线传感技术，故没有采样线缆，传输干扰被降到最低；另外，在安装于互感器和数字信号处理器上的无线收发器上配置的天线，可以提高传输可靠性和传输距离。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
下面结合附图和具体实施例对本实用新型进行详细说明。本实施例以本实用新型技术方案为前提进行实施，给出了详细的实施方式和具体的操作过程，但本实用新型的保护范围不限于下述的实施例。
如图1所示，一种基于无线传感技术的有源滤波装置，包括互感器1、数字信号处理器2和逆变器3，所述的逆变器3与数字信号处理器(DSP)2连接，所述的互感器1上安装有无线传感采样转换器4，所述的数字信号处理器2上连接有无线接收器5，所述的无线传感采样转换器4包括相连接的内置采集转换电路41和无线发送电路42，所述的无线发送电路42通过无线网络与无线接收器5连接，无线网络包括WiFi、GPRS或ZigBee。
上述有源滤波装置工作时，无线传感采样转换器4将从互感器1上采集的采样信号转换成数字信号，并通过无线网络发出，无线接收器5接收到该数字信号后传输给数字信号处理器2，数字信号处理器2根据接收到的信号控制逆变器3的输出，从而对谐波进行抵消补偿。
无线发送电路和无线接收器可配置发送天线和接收天线，以提高传输可靠性和传输距离。
