摘要:
A method and system for assessing or otherwise determining defective operation of an electronic control unit (ECU). The ECU may be a vehicle or non-vehicle ECU having any number of modules configured to provide and/or support any number of operations. The defective ECU operations may be determined as a function of a voltage drop across a shunt included on the ECU.

The invention relates to a base element (ST1, ST2, ST3) for receiving an overvoltage protective module (M1, M2, M3) for use in a bus system, having a first bus connection arrangement (BK1) for contacting a first bus potential (L1), a second bus connection arrangement (BK2) for contacting a second bus potential (L2), a third bus connection arrangement (BK3) for contacting a signal bus (L3), wherein the signal bus in a first state indicates the occurrence of a fault and in a second state indicates the non-occurrence of a fault, wherein a fault indicates a missing or incorrectly received or faulty overvoltage protective module (M1, M2, M3), wherein the first and second bus potential are to be used to supply arrangements on the overvoltage protective module (M1, M2, M3), wherein the base element further comprises an electronic monitoring arrangement (UE1), wherein the electronic monitoring arrangement (UE1) identifies whether an overvoltage protective module (M1, M2, M3) is received, wherein, if an overvoltage protective module (M1, M2, M3) is received in the base element (ST1, ST2, ST3), the second state is signalled via the signal bus, and, if no overvoltage protective module (M1, M2, M3) is received in the base element (ST1, ST2, ST3) or if the overvoltage protective module (M1, M2, M3) is received incorrectly or if the overvoltage protective module (M1, M2, M3) is faulty, the state of the signal bus remains unchanged, wherein the base elements (ST1, ST2, ST3) can be clipped onto a mounting rail (TS1, TS2), and the first bus potential (L1), the second bus potential (L2) and the signal bus (L3) are guided in a recess in the mounting rail (TS1, TS2).
摘要:
A distributed module control system for controlling a wind turbine using multiple controls and monitors comprising multiple modules that include microcontrollers, and having data input terminals and data output terminals; high level logic circuitry interconnecting the modules via selected data input and data output terminals; and certain modules also connected with the turbine monitors and controls to control operation of the wind turbines in response to monitoring of turbine operation.

A surge protection system provides surge protection to one or more circuits. Each circuit is connected to power and a surge protection module bridges the circuit such that the surge protection module absorbs surges from the power and/or the circuit. Being that, after exposure to certain amounts of surges, the surge protection modules lose effectiveness for surge protection, each surge protection module is independently removable and replaceable by a user without risk of personal injury from shock caused by making personal contact with the power and/or circuit. In some embodiments, a filter circuit is provided to filter out noise on the circuit. It is anticipated that the protection module includes indicators to inform a user that the protection circuit is operational and whether protection has been lost. Further, in some embodiments, a fuse is provided to protect the circuit from over current.

摘要:
An interface connector device for interconnecting a plurality of input/output devices including a signal bus connected to a control and to the input/output devices for multiplexing the signals between the control and the input and output devices, the bus interconnecting a plurality of interface and connector devices, and each of the interface and connector devices including address recognition circuitry as well as programmable configuration selection logic to configure the connector device to respond to a variety of input/output devices. In addition, the signal bus and connector devices are adapted to recognize and convey various levels of signals, for example, different voltage levels representing control information, framing signals, and diagnostic command signals.
摘要:
A generator system may include two or more generators electrically connected through a generator bus. A controller receives operation data from a first generator. The operation data may describe a power flow from a second generator to the first generator. From the operation data, either a loss of speed control or a loss of voltage control may be identified at the second generator. The controller may generate a command for the second generator based on the loss of speed control or the loss of voltage control.
