NOTE 1: The Internationa Electrical Commission (IEC) is the word wide only competent authority for international harmonisation of electrical standards and definition of corresponding terms. IEC has published this multilingual glossary under Electrpedia.

NOTE 2: The English term 'control' corresponds to the French 'commande' In most cases.

NOTE 3: I was active as electrical engineer for 40 years, e.g. responsible for international approvals and factory inspections. So I know the IEC terminology by heart.

As some doubts were put forward against the interpretation “C&P = Control and Protection”, given by the asker, I add some relevant links:

HVDC (High Voltage Direct Current Transmission System)
:
The main components of HVDC System include Thyristor Valve, Converter Transformer and Control&Protection System.
:
The main tasks of the HVDC plant consist of valve production, C&P test, type test(dielectric test and operational test) and routine test of thyristor valves.

ABSTRACT This paper describes the control and protection (C&P) system of the Basslink HVDC Interconnector project and in particular Win-TDC, the latest innovation from Siemens in the field of HVDC controls. The key aspects of the C&P structure and its redundancy are addressed. Reviews of measurement integration, monitoring, communication and time synchronisation, plus a brief overview of the design process (including off- and on-site tests) are also given.
Latest control and protection innovations applied to the Basslink HVDC interconnector. Available

The control and protection (C&P) schemes in the five-terminal MMC-HVDC system are more complex than are found in a two-terminal HVDC system.

DEF – An auxiliary cable used for measuring, control, protection and communication circuits.
OBS – Transportable fixed radiocommunications equipment for relief operations.
DEF – Câble blindé souple, comportant de 2 à 100 conducteurs, [qui sert] à la fois au transport de l'énergie (habituellement à une tension de 300 à 500 V) et de signaux basse fréquence pilotant le moteur ou le générateur pour commander le freinage, l'orientation ou la vitesse du rotor.
CONT – Nexans a fourni à NEG Micon 40 km de câbles de commande coupés avec précision, capables de résister à quatre torsions complètes par tronçon de 15 mètres, tout en offrant un rayon de courbure mobile minimal sur sa portion non tordue.
