Advanced Substation Gateway

Multi-function Controller Platform

GE’s G500 is part of the advanced Multi-function Controller Platform (MCP). This platform offers a high-capacity, secure, substation-hardened set of modular and expandable hardware and software components designed to simplify deployment, operation and maintenance of automation systems.

The MCP makes it possible for a single device to host multiple functions and applications such as Supervisory Control and Data Acquisition (SCADA) Concentrator, Remote terminal Unit (RTU), Human Machine Interface, Advanced Cyber Security Features, Non-Operational Data Storage among others. Consolidation of functions reduces the cost of deployment and operation while increasing system reliability through a reduced number of devices in the system.

Advanced Gateway
Advanced Automation
Fault Recording/Data Logging
Secure Access

The G500 is designed to provide a reliable and accurate collection of data (metering, status, events and faults) from serial or LAN based intelligent substation devices to master applications such as SCADA, EMS, DMS or other enterprise applications. With its modern and robust Cyber Security features, the G500 is designed for smooth integration into NERC CIP and Cyber Security environments while consolidating functions such as Ethernet communications, time synchronization, HMI and SCADA applications.

Key Benefits


Advanced Gateway Connectivity

The G500 collects data from substation protection, control, monitoring, RTU, and intelligent devices, pre-processes the data and moves it up to EMS and DMS SCADA systems providing centralized substation management.

Gateway features include:

Advanced Gateway Connectivity

G500 Advanced-gateway

Advanced Automation

The G500 provides the computing platform necessary to automate substation procedures, such that intricate processes are carried out safely and efficiently by creating advanced custom automation programs using IEC 61131 compliant tools, and perform basic math functions on data points using the built-in calculator tool.

Automation features include:

G500 Advanced-Automation

Fault Recording/Data Logging

G500 Fault Recording

The G500 can automatically retrieve event and oscillography files from devices such as Multilin UR Protective Relays, GE’s D25 Controllers, and IEC 61850 server devices. Using IEEE file naming standards, these event files are renamed and can be stored locally or securely sent to corporate servers using RSYNC, FTP or SFTP.

Using pass-through connections, users can extract valuable non-operational data such as digital fault recording (DFR) records, event and oscillography files. The user can also access the historical log files and upload the archived data for trending and analysis.

Fault recording features include:

Parallel Redundancy Protocol

IEC 62439-3 (Edition 2), Parallel Redundancy Protocol

Substation LAN redundancy has been traditionally accomplished by reconfiguring the active network topology in case of failure. Regardless of the type of LAN architecture (tree, mesh, etc.), reconfiguring the active LAN requires time to switchover, during which the LAN is unavailable.

Parallel Redundancy Protocol is an IEC 62439-3 data communication network standard which is often used to overcome single network failure without affecting the data transmission. PRP is independent of the communication protocols and provides no packet loss (“zero recovery time”) availability by using connected nodes which transmit and receive over two independent network active paths. Under PRP, each network node has two Ethernet ports attached to two different local area networks, using standard bridges, and similar topology.

The G500 can communicate simultaneously to devices connected to a common network, carrying mixed traffic: single LAN, legacy redundant or dual LAN, and PRP. This aids in implementing PRP in brown field installations, taking advantage of possible spare ports on existing managed switches LAN infrastructure.

Secure Remote Access

G500 provides robust security environment, providing seamless integration with existing IT department policies. Role based Access Control, Secure Web Interface, Secure File Transfer, and extensive user activity logging provide a complete security toolkit required to achieve NERC-CIP compliance.

Secure remote access features include:

G500 Secure-Access


Online-based Configuration

The G500 can be configured remotely through the use of a simple user pre-defined drop down lists of device point maps.

Offline-based Configuration

Alternatively, the G500 can be configured using an excel-based bulk editor. This offline configuration capability improves the flexibility and increases productivity for users configuring large number of database points.

IEC 61850 Substation Device Loader

A key benefit to using IEC 61850 based communications is the reduction in deployment costs for modern substation automation systems. The G500 IEC 61850 loader application guides users through a structured 4-step workflow to configure the IEC 61850 client application, reducing system configuration time.

Device Configuration

Configuring the G500 to communicate with substation devices is simple and straightforward. Thanks to pre-configured map files, adding devices to the system only takes a few mouse clicks. Point maps can be customized to meet your specific needs, then applied for all devices requiring the modifications.
