6、on interfacing for digital protection equipment and related control and monitoring devices to be used in the same electrical installation. This standard gives general information about the functional levels in a hierarchical structure and about the typical organisation of devices communicating in an
7、 open system. In this standard, an electrical installation refers to substations for voltage levels above 1 kV and power stations. Communication outside a particular electrical installation (for example communication between a substation and a remote control centre or another substation) is outside
8、the scope of this standard. Communication between dedicated devices provided by the same manufacturer, for example differential protection schemes, is outside the scope of this series of standards. 2 Normative references lhe following normative documents contain provisions which, through reference i

18、s of the electrical installation); d) measurands; e) fault information, for example from protection devices; 1) parameter information (settings, etc.). 5 Typical structure of a hierarchical system 5.1 Structure of a hierarchical system Figure 3 shows a typical functional structure of an electrical i
19、nstallation (for example an EHV/HV substation) organised in a hierarchical system. There are three functional levels: BSI BS*EN*bL733- II 96 I1624669 0545646 205 = Page 7 EN 61733-1 : 1996 a) level O: process level this level includes the primary equipment (instrument transformers, circuit breakers,
20、 disconnectors, etc.). b) level 1: unit level this level includes functions directly related to primary equipment, for example: - monitoring and metering; - protection; - automatic reclosing; - control. c) level 2: substation level this level includes common substation functions, for example: - moni
21、toring and metering; - control; - telemetry and telecontrol. 5.2 Information exchange Figure 3 shows a block diagram of a typical EHV/HV substation. The information (analog and/or digital) can be exchanged between devices operating at the same functional level or between devices operating at differe
22、nt functional levels. The communication between devices may be achieved by either conventional point-to-point connections (medium: multicore cable) and/or a communication network. 6 Communication system arrangement of an electrical installation 6.1 De vice communication The secondary equipment of an
23、 electrical installation includes a number of functions. Each device includes at least two important parts, as shown in figure 4: - communication machine; - application machine. The communication machines connect two or more application machines, via an interface and medium, to allow the exchange of
24、 information. In order to allow the above-mentioned exchange of information, the transmission protocol(s) shall be compatible, in all cases where communication between devices of different manufacturers is required. The communication machine as shown in figure 4 usually includes both hardware (commu
