Main Tasks:Is a High Level Control protecting and coordinating the generation-
transmission system.Re-distribute the active power between Bipole 1 and Bipole 2 upon loss or
limitation of HVDC transmission capacity. Re-distributed the active power from the BtB to Poles in operation upon loss
or limitation of the Back to Back transmission capacity. Avoid self excitation of the generators in Jirau and Santo Antonio by limiting
the maximum amount of filters connected to the 500kV AC-network.Reduce possible overvoltage on the 500 kV AC-networks by disconnecting
AC-filters.Balance and control the reactive power exchange between the HVDC
converter station and the corresponding AC-network.Restoration of active power balance at DC/AC-related limitations (Porto
Velho 500 kV AC and Araraquara 500 kV AC network).

• Faults at Rectifier;• During switching of transmission lines or equipment belonging to the
Converter Stations;• For voltage drops with the final value not below 85% in all phases.
CONCLUSION - MAIN DIFFICULTIES
15
A. Deadlines: Very complex project – 3 months for the submission of the basic design projects and a period of 4 months for the review and approval of their conformity with the Technical Annex were not enough.
B. Technical Specification vs. Functional Specification : equipment acquisition was based on the Technical Annex, which does not detail adequately the technical characteristics of equipment to be supplied by manufacturers. It is believed that this was one of the aspects that required most of the discussions on the interpretation of technical requirements during the basic design.
C. Division into Lots: There is no doubt that the division of the transmission installations into lots for the auction process is a pillar to increase competitiveness and thereby achieve low tariffs. However it imposes some difficulties:The sharing of the converter reactive compensation and the AC filters;The compatibility of the insulation levels of the several installation connected to the same AC switchyard;The operational interaction required by control and protection schemes
D. The absence of coordination in charge of conducting the necessary compatibility of requirements, deadlines and concerns from agents who share the facilities.
E. Confidentiality Aspects .
Division into LotsPossible Main Alternatives
17
A.Just one Lot: Technically the bestB.Same bipole as a Lot C.All the convertors at the same station as a Lot
Pros and Cons - Alternatives B and C
18
B. Same bipole as a Lot Clear owners identification of each bipoleMore guarantee of time schedule of each bipoleLower possibility to optimize filters and reactive compensation design
C. All the convertors at the same station as a LotLower necessity of sharing of installationsSimpler coordination at the same converter station, avoiding complex coordination between filter design, insulation coordination and control philosophiesEnabling duplication and scale earningPre-existance of successful commercial experienceSome concern about coordination of controls between rectifier and inverter terminals belonging to different owners
