Smart-Gear® Power Distribution Solution (PDS)
Smart-Gear® Power Distribution Solution (PDS)
Description
Siemens, a world leader in innovative technologies, has taken another step forward by creating the total solution in medium-voltage switchgear.
In response to our customers' need for standard switchgear that is programmable and self-monitoring, Siemens has combined its advanced switchgear, protective relay products and its engineering experience to deliver a total package to customers: Smart-Gear® Power Distribution Solution (PDS).
Smart-Gear® PDS combines Siemens switchgear type GM-SG non-arc-resistant 5 kV-15 kV, type GM-SG-AR arc-resistant 5 kV-15 kV or type GM38 non-arc-resistant 38 kV and Siemens SIPROTEC® protective relay technologies to offer one of the most advanced standardized switchgear solutions in the industry.
With its standard self-monitoring features and programmable capabilities, Smart-Gear® PDS redefines how switchgear is specified, engineered, operated, installed and maintained.
Features
Smart-Gear® PDS is equipped with standard self-monitoring features, designed specifically to enhance the performance and reliability of the switchgear. With Smart-Gear® PDS, the user is notified in advance of potential problems such as those in trip circuit and space heater circuits. Also, based on the usage of the equipment, the user will be notified when periodic recommended preventative maintenance is needed.
Using IEC 61850 communication protocol, all control, monitoring and protection functions are accomplished through a redundant fiber-optic connection between protective relays and bay controllers. This communications capability reduces the need for much of the control wiring necessary to implement and change complex schemes, resulting in reduced field testing and commissioning time.
With Smart-Gear® PDS, users are provided the following features and benefits:
- Reduced control wiring for increased reliability - digital and fiber-optic circuits instead of hard-wired circuits
- Self-monitoring - feature-rich increased operational reliability
- Programmable - easy to implement complex schemes with flexibility for future changes
- IEC 61850 communication protocol providing integrated control, monitoring and protection
- Usage-based preventative maintenance
- Faster commissioning and start-up.
Types SG-64 and SG-80
Types SG-64 and SG-80
Smart-Gear® PDS is provided with standard features designed to monitor the critical functions and controls of the type GM-SG, type GM-SG-AR or type GM38 medium-voltage switchgear. Options can be selected to increase functionality.
Smart-Gear® PDS is available in two types: SG-64 and SG-80. The specific functionality of the self-monitoring features are dependent on the Smart-Gear® PDS type selected.

Application-Based Specifying
Application Based Specifying
An application-based approach to configuring switchgear offers a new way of thinking. For example, with an application-based approach, all switchgear functions including automatic transfer schemes, circuit breaker types, protection schemes and other special switchgear functions are described in terms of application modules. When combined, these application modules define the operation and configuration of a Smart-Gear PDS® solution.
All software programs and digital and hard-wired circuits used to perform specific operations or protective functions are referred to as "apps," which are protective relay hardware and software programming (continuous function chart (CFC) programming) designed specifically for application modules.
Application modules are the building blocks used for configuring a Smart-Gear® PDS switchgear lineup. These modules are pre-configured applications designed to perform specific functions.
There are five classes of application modules:
- System application modules
- Auxiliary application modules
- Circuit breaker application modules
- Remote control application modules
- Special application modules.
Instructions for Specifying
Instructions for Specifying
With Smart-Gear® PDS, specifying medium-voltage, metal-clad switchgear is easy. All of the information can be found in "The complete application guide to specifying a Smart-Gear power distribution solution (PDS)" (E50001-F710-A123-V1-4A00) available electronically in the Product Literature - English.
System Modules
System Application Modules
System application modules are used to define the operation and protection of the entire switchgear lineup. All automatic transfer and circuit breaker interlock application modules are implemented with CPC programmed protective relays, IEC 61850 communications over fiber-optic cable. System application modules include:
- Automatic transfer
- Circuit breaker interlocking
- Protection.
Auxiliary Modules
Auxiliary Application Modules
Auxiliary application modules are defined by the type of auxiliary device in the compartment and their configuration. Auxiliary application modules include:
- Voltage transformer
- Control power transformer.
Circuit Breaker Modules
Circuit Breaker Application Modules
Circuit breaker application modules are defined by the functional requirement (or load type) of a circuit breaker.
For Smart-Gear® PDS, there are eight basic circuit breaker application modules. These application modules include main, tie, motor feeder, transformer feeder, distribution feeder and capacitor feeder applications and equipped space or future cell modules.
Each circuit breaker application module (except future cell) is fully equipped with the relay protection necessary to meet the protection requirements of the specific application and functions of the circuit breaker.
