摘要： The present disclosure is directed to a method for protecting an electrical power system connected to a power grid. The electrical power system includes at least one cluster of electrical power subsystems. Each of the electrical power subsystems defines a stator power path and a converter power path for providing power to the power grid. The converter power path includes a partial power transformer. The electrical power system further includes a subsystem switch configured with each of the electrical power subsystems and a cluster transformer connecting each cluster of electrical power subsystems to the power grid. A cluster switch is configured with the cluster transformer. A controller is communicatively coupled to each of the plurality of electrical power subsystems. Thus, the controller monitors the electrical power system for faults, and if a fault is detected in the cluster, sends, via one of the subsystem switches or the power converters, a block signal to the cluster switch.

摘要： An example method for detecting and mitigating attacks on electric power substations comprises detecting a command to open or close a circuit breaker in the electric power substation. A modified extended substation model for the electric power substation is generated, based on the detected command and based on measurements in substation, where the modified extended substation model is a power flow model for the substation and for one or more directly connected neighboring substations. A power flow analysis is performed, using the modified extended substation model, to generate a predicted voltage for each of a plurality of nodes in the substation and in the one or more directly connected neighboring substations. Each predicted voltage is compared to a corresponding allowable voltage range, and execution of the command is blocked in response to determining that one or more of the voltages is outside the corresponding allowable voltage range.

摘要： A method of determining a communication time delay in a communication network between a local terminal and one or more remote terminals within an electrical power network includes: selecting, in respect of the or each remote terminal a calculation node in the electrical power network; calculating respective node currents flowing into the corresponding calculation node from the local terminal and the or each remote terminal; equating, in respect of the or each remote terminal, a sum of node currents flowing into the corresponding calculation node to zero according to Kirchhoff's first law; and extracting, in respect of the or each remote terminal, a communication time delay between the local terminal and the said respective remote terminal from a corresponding equated sum of node currents.

摘要： A method of clearing a fault in a high voltage DC electrical network, including power converters interconnected by a DC power transmission, comprising: detecting a fault in the DC power transmission and reconfiguring each power converter to a fault blocking mode drinving the DC fault current towards zero; locating the fault and isolating a faulty portion from a healthy remaining portion; reconfiguring one of the power converters designated as a re-energising power converter from the fault blocking to re-energise the healthy remaining portion; and detecting a rise in the voltage level in the healthy remaining portion above a threshold level and reconfiguring the remaining power converter connected with the healthy remaining portion from the fault blocking to the normal power transmission.

摘要： A protection device, externally connectable to an existing circuit breaker with zone selective interlock functionality, enables a circuit breaker to implement directional zone selective interlock. The protection device includes a first input port and a first output port connectable to a circuit breaker, and second and third ports for connecting to a protection device of another circuit breaker and for transmitting interlock signals via an input bus and an output bus inside the EDP. A control unit is configured to enable one of the second and third ports as a second input port and the other as a second output port according to the direction of current currently flowing through the circuit breaker; and configured to forward an interlock signal from the first input port to the output bus and to forward an interlock signal on the input bus received from the second input port to the first output port.

摘要： Automatic reclosing of a fault interrupting device is overridden by establishing communication with a control system for a fault interrupting device operable to open responsive to a fault on an electric distribution system and automatically reclose after a predetermined time delay, and analyzing data for the electric distribution system by an apparatus separate from the fault interrupting device control system and having higher performance than the fault interrupting device control system, to determine whether to block the automatic reclosing of the fault interrupting device before the fault interrupting device automatically recloses. An autoreclosing block command is generated by the apparatus if the apparatus determines the automatic reclosing of the fault interrupting device should be blocked. The autoreclosing block command is sent from the apparatus to the fault interrupting device control system to prevent the automatic reclosing of the fault interrupting device after the predetermined time delay.
