基于连通状态矩阵的智能变电站安措校核方法
|
摘要
智能变电站采用网络通信模式,其二次安措具有操作对象复杂、隐含不直观的缺点,安措票的正确性难以保证。首先基于变电站配置描述(SCD)文件、IED能力描述(ICD)文件和光纤物理回路描述(SPCD)文件等模型文件,建立智能变电站二次设备的静态拓扑模型,然后读取二次设备的相应状态,进而提出基于二次设备连通状态矩阵的智能变电站安措校核方法。该方法读取安措操作的步骤集合,对安措操作的每一步进行操作校核,检验该操作是否会造成保护的误闭锁或误动作,在操作校核通过后,再进行安措隔离校核,检验检修设备和运行设备之间是否实现了有效隔离。通过某变电站事故和某220 kV智能变电站的算例,证明了所提安措校核方法的有效性。
Due to the application of network communication for smart substation,the security measures of secondary equipment become implicit and complicated,which makes it difficult to verify correctness of the security measures. A strategy for the verification of security measures for smart substations is proposed. Firstly,based on SCD(Substation Configuration Description) file,ICD(IED Capability Description) file and SPCD(Substation Fiber Physical Circuit Description) file,the static topology model of the secondary equipment for smart substations is constructed,and then the corresponding state of the secondary equipment is read. Then the verification method for security measures of smart substations based on communication state matrix is proposed,which reads the step set of security measure ope-ration,checks each step of the security measure operation and checks whether the operation will cause mis-locking or mis-action of the protection. On the basis of the security measure operation verification,the isolation verification is performed to verify whether the effective isolation between the inspection equipment and the operating equipment is implemented. Through the case study of a substation accident and a 220 kV smart substation,the effectiveness of the proposed verification method for security measures is verified.
