摘要:
Methods and systems for modifying a turbine control system may be provided for. A method may include replacing at least one legacy main controller processor communicating in a first communication protocol with a current main control processor communicating in a second communication protocol, retaining at least one legacy IO processor in communication with at least one turbine monitoring device communicating in the first communication protocol, and providing at least one converter in communication with the current main controller processor or processors and in communication with the legacy IO processor or processors. The converter may translate communications between the current main controller processor or processors and the legacy IO processor or processors by translating between the second communication protocol and the first communication protocol.

Fast detection of contact status with an AC wetting voltage using a ratiometric approach is described herein. In one embodiment, a voltage source wets the contact with a wetting voltage. A contact voltage monitor receives voltage obtained from the contact and converts the voltage to a first frequency output. A wetting voltage monitor receives wetting voltage provided from the voltage source to the contact and converts the sensed wetting voltage to a second frequency output. A processor generates a ratio between the first frequency output and the second frequency output and determines the status of the contact and the field wires associated with the contact in accordance with the generated ratio.

A redundant control system for controlling an electromechanical system is provided. The control system includes a first processor, a second processor, an input-output node, a first communication channel, a second communication channel, and a signal selector. The first and second processors have a control algorithm and state variables resident thereon. The first and second processors each generate an output signal based on the control algorithm, the state variables, and an input signal from the electromechanical system. The first communication channel communicates the input signal and the output signal between the first processor and the input-output node, while the second communication channel communicates the input signal and the output signal between the second processor and the input-output node. The signal selector communicates either the output signal from the first processor or the output signal from the second processor to the electromechanical system.

An apparatus and method for mounting electrical devices in a housing at an angle relative to the ground is provided. The apparatus comprises a housing having a top, bottom, and sides, each of which may be open, closed or ventilated. One or more electrical devices are located in the housing and are oriented at an angle relative to the horizontal ground. The electrical devices may be silicon controlled rectifiers that serve as a power bridge between an exciter and a power generator. A method for mounting electrical devices in a housing at an angle relative to the horizontal ground is also provided.

A control system having a host computer and one or more control computers connected to an interface for control of a process or machinery. The control computers are capable of automatically initiated network address assignment and configuration when powered up after installation. The network address is based on a location identifier situated in the interface that corresponds to a specific connection thereof to the control computer. The control computer reads the location identifier from the interface and requests a network address. The host computer assigns the network address based on the location identifier. Configuration of the control computer then proceeds. The procedure applies to newly installed control computers, whether first time installment or a replacement for a failed control computer.

Systems and methods for providing time synchronization in a local network are provided. A time source may be configured to determine a current time and a designated time at which a reference signal will be output, and to output the reference signal when the designated time is reached. A network host communicatively coupled to the time source may be configured to (i) identify the designated time and (ii) communicate the identified designated time to one or more network devices via a local network. The one or more network devices may be respectively configured to (i) initiate an internal clock, (ii) receive the designated time from the network host, (iii) receive the reference signal output be the time source subsequent to receiving the designated time, and (iv) set a value of the internal clock to the designated time upon receipt of the reference signal.
