An Electrical Mine Monitoring System Utilizing the IEC 61850 Standard

Abstract

Motor control assets are foundational elements in many industrial operations. In the mining industry, these assets primarily consist of motor control centers and drives, which are available with a comprehensive assortment of control and monitoring devices. Various intelligent electronic devices (IEDs) are now used to prevent machine damage and downtime.As motor control devices have advanced in technology, so too have the IEDs that protect them. This dissertation investigated the steps involved in interfacing IEDs to a mining process control network via the use of the IEC 61850 standard. As a result of this study, several key technological advancements were made including the development of (i) vendor independent system to communicate with IEDs in a mining environment over IEC 61850, (ii) command and control methods for communication based assisted automation of IEDs for mining firms, (iii) effective solutions to incorporate electrical distribution data in the process control system, (iv) enhanced safety platforms through remote operation of IEDs, (v) standard visualization faceplate graphics for HMI operators with enhanced security, and (vi) new methods for time stamped dataflow to be correctly inserted into a process historian for "true" Sequence of Events Records.iii | P a g e

Enhancing traditional process SCADA and historians for industrial & commercial power systems with energy (via IEC 61850)

“…Previous research and advancements in technology have created a society where companies want to collect a large amount of real-time data, sort this data, and with the advent of the discrete event data tum this into actionable information [1,2]. Now, there is a push to archive this discrete data so that it can be trended at a later time, as well as used for modeling of the overall process.…”

“…In the past four years, research and application examples with the IEC 61850 standard have become more prevalent [2,3,[5][6][7]. These examples and applications show that an Ethernet based standard such as IEC 61850 can be used for protection, command and control, and SCADA gathering of data over the same redundant wire pair [8][9][10][11].…”

“…As this "real time" data is provided to the central controller or SCADA master in the system graphics can be populated to alert engineers and operations to system status [3,6]. Additionally, this data can be used to make command and control decisions in an industrial application [5].…”

“…An example of this logic is shown in Figure 3. Figure 4 shows the configuration of the ALMD instruction with the associated lED timestamp (1) and point ID (2). It is important to note that the severity is set to 200 (default 500), in order to provide the control system a way to differentiate tags as electrical distribution tags.…”

“…For safety regulations, it is prohibited the installation of instruments at the shovel during its operation [4][5] [6]. Therefore, the worst-case condition requires computer modeling.…”
