MDS Intrepid: 25 Mbps Full Duplex/50 Mbps Aggregate Throughput 

The Intrepid backhaul solution provides up to 25 Mbps full duplex/50 Mbps aggregate throughput. Featuring a wide range of options, the Intrepid is available as a compact IDU unit with two Ethernet ports and two T1/E1 ports, or as a 19" rack mountable IDU unit with two Ethernet ports and up to 8 T1/E1 ports.

MDS Intrepid Ultra: 100 Mbps Full Duplex/200 Mbps Aggregate Throughput 

The Intrepid Ultra provides 100 Mbps full duplex/200 Mbps aggregate throughput, and is available as a compact IDU unit with two Ethernet ports and two T1/E1 ports, or as a 19" rack mountable IDU unit with two Ethernet ports and up to 16 T1/E1 ports.

The SDxP is used when applications demand no single point of failure for the communications system. The MDS SDxP incorporates two MDS SD transceivers and power supplies with automatic or manual switchover capability. On detection of a failure, the MDS SDxP switches immediately to the standby transceiver. The switchover occurs for selectable transceiver alarm conditions. Switchover also occurs when no valid packets are received in a time frame of 1–30 minutes, or upon loss of power to the operating radio. An internal backup battery is provided in AC-powered models for continued operation during a loss of primary power.

The SDA adaptor is used with 4790 and 9790 Master Stations to add IP/ Ethernet connectivity and SD features. The SDA can be ordered with new Master Stations or easily added to equipment already installed. Once connected to a 4790/9790, one (1) serial port and one (1) Ethernet port are available for connection to external systems or devices.

The MDS Master Station is used in a various operational settings depending upon the users specific use case including Master, streaming Repeater or polling Remote. In addition to full duplex, both half duplex and simplex modes are configurable by the user.

Typically, the Master Station is located where the primary connection to the user's host system or network is made. In many instances however, clear RF line of sight to remote radio locations cannot be achieved at control centers or host system connection point. In these cases the Master Station can be configured as a streaming Repeater and located at optimal tower sites where line of site can be achieved. An additional Master Station is then configured as a polling Remote. Host system communication is then achieved at the polling Remote through the Repeater to all remote radio locations.

Master, Repeater or Polling Remote

The MDS Master Station can be configured as a Master streaming Repeater and Polling Remote when frequency plans and tower locations and RF line-of-site considerations drive flexibility in enterprise network connections.

Ease of maintenance and serviceability are two additional benefits derived from our modular communications platform. All components in the MDS Master Station are easily accessed from the front panel eliminating the need to remove the chassis should module replacement be required. In addition, redundant transceivers and power supply modules are hot swappable to ensure that the MDS Master Station remains fully operational during service periods after a failover.

All power, serial and Ethernet connections are made to the front panel. Antenna and external filter connections are made in the rear of the unit.

Controlled switching of multiple loads

CSD100 is an advanced controlled switching device for high voltage AC circuit-breakers for any kind of application.

Challenges

Depending on substation architecture, one single circuit-breaker will operate different loads. Maintain optimal performance in such situation is a real challenge.

One single Controlled Switching Device per Circuit-breaker

GE Vernova has developed for the CSD100 a multiple load switching feature, allowing to use one single device per circuit-breaker.

• Whatever the substation architecture with tie circuit breaker or meshed arrangements
• Whatever the operating mode, for example:
  • Power plant black-start from the grid (line or cable)
  • Compensated line or only grid compensation with shunt reactor
  • Variable neutral position (or grounding) for compensation asset

The positions of the substation apparatus (circuit-breakers, disconnector switches) define the load to switch. The CSD100 selects the programmed switching strategy accordingly.

Benefits:

• Controlled operations of single circuit-breaker siwtiching several loads
• Useful for any kind of substation architecture/configuration
• Switching strategy automatically adapts to the real time
