1 Scope

NB/T 10132-2019 fixes what a communication design for a hydropower project must contain, and to what level of detail, at each stage of the design process, replacing DL/T 5184-2004. It is not a technical code telling the engineer how to size a system: it is the document that tells them what must be delivered, so that a design submitted for review can be judged complete. The regulation sets the general provisions and the defined terms, then works stage by stage - planning, pre-feasibility, feasibility, preliminary design, tender design and construction drawings - and for each stage it lists the chapters the design report must contain, the calculations and analyses that must be presented, the drawings and their scales, the equipment and material schedules, and the estimates. The subject matter covered runs across the whole communication scope of a hydropower scheme: the system communication linking the plant to the dispatch centre, the plant-internal communication with its exchange and terminals, the administrative and production networks, optical fibre cable routes along the transmission line and within the site, microwave and satellite links where they are used, the dam and reservoir communication including flood warning, emergency and mobile coverage underground, and the power supply and earthing for the communication equipment. It applies to hydropower design institutes working in China.

Chapter 1 states the purpose, the field of application and the general relationship of this Regulation to the wider body of design standards. It occupies page 1 of the standard and is composed of four provisions numbered in the 1.0.x series used by Chinese design regulations.

1.0.1 This Regulation is formulated in order to unify the content and the depth of communication design for hydropower projects.

1.0.2 This Regulation applies to the communication design of newly built, reconstructed and extended hydropower projects.

1.0.3 The division of the communication design into stages shall be consistent with the division into design stages of the hydropower project to which the communication design belongs.
