Patent

CA 2638049

The present invention refers to a device that has the capability to operate as an Acquisition, Control and Measurement element in an Electrical Distribution of Average Tension Network or in Electrical Substation, operating as master device (initiates the communication) or slave (responds the communication) in SCADA (Supervisory Control and Data Acquisition) systems. The device of the invention has the capability to process logical states and analogical signals, such as parameters of flow and voltage, frequency and power, having also the capability to handle digital outputs by means of relay contacts and optoisolated digital inputs. The device of the invention can be used to simultaneously interconnect control equipment into diverse systems of Acquisition through its communication ports and standard communication protocols such as DNP, Harris 5000/6000. It allows that remote devices access its data base through TCP/IP, RS-232, RS-485, Modem GPRS, Modem FSK, connections, practically using any means available, Radio, telephone, audio, cellular, Internet, Intranet or cable. It can be used like data concentrator and/or protocol translator, includes a virtual connection of the transparent port type for communication towards other devices that manage solely Proprietary software without data conversion through anyone of its communication ports. Includes a maintenance port and three type RS232 / RS 485 data ports, in addition includes ports for interconnection of expansion modules. It has two 127 VCA feeding inputs that operate like redundancy one of the other, additionally includes a battery pack that enters into operation in total absence of the 127 VCA feeding. It also includes a configuration and maintenance software, that carries on its functions through a visual interface in Windows environment, compatible with Windows 98/2000/XP. Incorporates functionalities management for measurement of energy quality, it has the capability to detect an overload fault in the line of average tension and immediately send the alarm towards the Master Central Unit that is monitoring it so it can analyzed the provided information and takes the necessary actions to isolate the fault and recovers the failed section of the circuit of the Electrical Network operating remotely the involved relay switch. It has the capability to carry out automatism of auto sectionalization in the Distribution Network of average Tension by means of operation logics denominated Control Voltage Time, CVT and special hardware, exclusively based on the detection of voltages both from the Source as well as of from the load side.
