The present disclosure relates to exemplary systems for providing control and expert services over a communication network by specialized service providers to various kinds of automation needs and methods thereof. The arrangement allows sharing of automated control system components among one or multiple users. Methods to configure and use control and automation service are also described. Exemplary systems for control and automation service as disclosed herein can have greater flexibility and simplicity from the plant user perspective.

System and a method for control and automation service

A method and system are disclosed for optimizing load scheduling for a power plant having one or more power generator units. An exemplary method and corresponding system can involve detecting an event indicative of a need for adapting one or more constraints for an objective function used in load scheduling. On such detection, the objective function is analysed to determine adaptive constraint values for the one or more constraints for optimally solving the objective function. These adaptive constraint values can be used to solve the objective function and the solution of the objective function with the one or more adapted constraint values can be used to operate the one or more power generation units of the power plant.

Process optimization method and system for a power plant

A method and control system are disclosed for optimizing load scheduling for a power plant having one or more generation units. The method can include analyzing the operating state of one or more components of generation units in terms of one or more risk indices associated with one or more components of generation units; updating an objective function that reflects the state of one or more components of generation units; solving the objective function to optimize a schedule of the one or more generation units and operating state of one or more components of generation units; and operating the one or more generation units at optimized schedule and operating state.

Method and control system for scheduling load of a power plant

A relay interface module that is commutatively connectable to at least one I/O device and a controller, wherein the relay interface module is configured to provide data from the I/O device to at least one controller in a distributed control system (DCS) via a communication interface. An application related to a particular I/O device may then be executed freely on any controller present in a DCS without losing real time connection with the associated I/O device. Data can be transferred from an I/O device to an associated application executed on a controller such that the real time connection between the I/O device and the application being executed is maintained.

Relay interface module for a distributed control system

A power distribution management system is disclosed for optimal power distribution for a predetermined class of loads and other loads. The power distribution management system include a substation for distributing power supply to a load network, where the load network includes the predetermined class of loads and other loads and the substation includes a plurality of feeders. The power distribution management system includes an optimizer for generating an optimal load schedule for a control period for the predetermined class of loads. The power distribution management system also includes a communication interface for communicating between the plurality of individual loads and/or the optimizer.

Load scheduling optimization in distributed system

An exemplary method and system are disclosed for coordinated transfer of control in a substation system having IED or logical devices/servers using GOOSE messages with preconfigured data models with logical nodes containing one or more data objects including private data objects (DO) connected in the substation communication network. The method for transfer of control can be illustrated for hot-standby device management and for other applications such as logical isolation of merging unit in a substation and load sharing between IEDs. The method can be used for devices that do not have MMS stack.
