Abstract: Methods and systems for secured control of circuit breakers in an electric power substation against undesired direct operation. Consequences of a malicious action are prevented or mitigated using a validation approach that either blocks the command or ensures a negligible effect on system operation. An example method, suitable for implementation in a monitoring device in an electric power substation, includes receiving a command to open or close a circuit breaker. In response, one or more state parameters for the electric power network that comprises the substation are then predicted, the predicted state parameters reflecting an operating state for the network under the assumption that the received command is executed. The method further comprises comparing the predicted one or more state parameters to corresponding operational limits. Execution of the command is then blocked, in response to determining that one or more of the predicted state parameters violate the corresponding operational limits.

Abstract translation: 电力变电站断路器的安全控制方法和系统，防止不必要的直接操作。 使用验证方法阻止或减轻恶意行为的后果，该验证方法阻止命令或确保对系统操作的影响微乎其微。 一种适用于电力变电站监控装置实施的示例性方法，包括接收断路器的断开或关闭命令。 作为响应，然后预测包括变电站的电力网络的一个或多个状态参数，在假定接收到的命令被执行的情况下，反映网络的操作状态的预测状态参数。 该方法还包括将预测的一个或多个状态参数与相应的操作限制进行比较。 响应于确定一个或多个预测状态参数违反相应的操作限制，则该命令的执行被阻止。
