摘要
介绍一种包含多个异构子系统的大型变电站综合自动化集成系统,各系统负责采集数据并传输到电站,中央控制室根据各设备运行情况统筹管理。描述了异构系统的数据交换以及数据传输的处理过程,并提出了一种多通道数据传输的策略,根据数据的用途及性质,采用数据分类分通道传输,各通道间彼此独立,互不干扰。现场运行结果证实:该方法提高了整个网络系统的实时性,降低传输带宽要求,保障了数据通讯的稳定性。
A microprocessor-based protective system is introduced in this thesis.It is composed of several heterogeneous subsystems which acquires data and sends them to the power plant.Then the decision is made by the central control station according to the situation of the subsystems.Data exchange between heterogeneous systems,dada compression and decompression are discussed and a new method about transferring dada in multi-channel is put forward. According to the character and usefulness,the dada are sorted and sent in separate channels.The result on-site confirms that the method can improve the real-time performance,reduce the requirement of the bandwidth and maintain the stability of the communication.
