Sobre el proyecto
Client: Chaglla Hydroelectric
Year: 2020
We implemented secondary frequency regulation in Chaglla. The Secondary Regulation is a complementary service promoted by the COES, which allows adjusting the generation with the objective of maintaining the frequency in the system in its reference value in order to avoid that the frequency goes out of the allowed range and thus avoid that a large part of the population is left without electricity.
The implementation consisted of a bidirectional information exchange between the SCADA system used by the Generation and the SCADA system in IEC104 protocol. Finally, the SCADA will send and receive the signals from the COES SCADA.
With this implementation, the COES qualifies the Chaglla Hydroelectric Power Plant as suitable to perform the secondary regulation service. Likewise, the COES will make the payment of the amount of compensation associated with the scheduled Generation units for providing the secondary regulation service.
Stages of the project:
Stages of the project:
– Configuration of sending and receiving signals to the SCADA of the CHAGLLA generator.
– Configuration of send and receive signals to the COES SCADA using IEC104 protocol.
– Communication channel switching tests were performed. With the channels connected, the main channel was disconnected and the re-establishment of data transfer through the secondary channel was verified.
– Signal verification: reception of analog signals and states from the secondary regulation unit, as well as the sending of setpoints.
– Load/unload tapping speed test. Upper and lower generation limits defining the band available for Secondary Regulation of the group (LSR, LIR).
