DLR Line 2x500kV
2X500kV CHANGOS-KIMAL LINE
The high voltage line corresponds to a double circuit in 500KV, with an approximate extension of 140Km that connects the Changos and Kimal substations. The line has 289 torres, where each phase corresponds to an arrangement of 4 drivers, also, has an OPGW guard cable.
THE PROJECT
The project is based on the implementation of 5 line monitoring points or DLR (Dinamic Line Rating), based on the use of the mosdorfer OTLM line sensor and Lufft weather stations.
The proposal was based on compliance with the definitions of the National Electric Coordinator, which established by decree that the project had to comply with 5 line monitoring points.
The design and engineering proposed by Active Control established the location of the 5 monitoring points distributed in such a way as to cover the spans or critical points of the line, and a uniform distribution was offered that would allow the end operator to have an overview of the line.
The project architecture considered the use of the following equipment:
- 10 OTLM line sensors (2 per monitoring point).
- 5 weather stations.
- Wi-Fi communication between OTLM sensors and field cabinets.
- Fiber optic communication between the monitoring points and the Sub-Station (SSEE).
- A central cabinet located in SSEE as a data concentrator (software central OTLM Smart Center).
- IEC communication 60870-5-104 towards SICAM team.
The communication architecture designed consists of a ring distribution that has a sensitivity of -37db between transmission and reception..
Además, Each monitoring point has a solar panel design and a battery arrangement to ensure the autonomy of the system..
The use of state-of-the-art technology, with high performance and low consumption equipment, allow to reduce the design of the backrest system, which translates into the use of a single cabinet per monitoring point, reducing the weight that the tower must support, and facilitating assembly activities.
