EPRI, Palo Alto, CA, 2006. 1014781. iii ABSTRACT This technical update describes the status of effort to date on two first tasks of the project with Polish transmission system operator (PSE-Operator) to help define needs for IntelliGrid-based architecture, an enhanced electricity delivery model that is expected to dramatically improve power line reliability and capability. The tasks were performed at the northern part of the national grid system in Poland. Task 2: Telecommunications Infrastructure Assessment This task involves investigating the existing telecommunications infrastructure and comparing the results with requirements obtained in Task 1 to determine if any changes or additions are required to implement those requirements. Potential issues include bandwidth, latency, network management capability, and security. EPRI considers this project pivotal because it represents the first demonstration of how to transform the electric grid into more responsive and resilient delivery system and that will prove vital as the utility industry plan, designs, upgrades, and replaces equipment that will serve customer needs over the next 40 to 50 years. v ACKNOWLEDGEMENTS The authors and the project managers would like to express appreciation to the following individuals who generously contributed their time and knowledge to the development of this report.

These concentrators will send collected data received from substations (for example from measuring transformers, relays and also from ARNE and SSiN systems) to the M&VSP System server that will be installed at the dispatching center in PSE North (ODM Bydgoszcz). If the SSiN substation system is the only data source at a selected substation, this system will directly send data to the server. The proposed system configuration is shown in Figure 1-1. Figure 1-1 Proposed System Configuration 1-1 The data sources (e.g. Data Concentrators, SSiN systems) and the data communication system connecting these concentrators with the server have to fulfill the following requirements: • • Data updating cycle has to be no longer than 1 s The total data transmission delay (i.e., the sum of communication network delay, data processing delay at a given substation and data processing delay in the server) has to be no longer than 1 s • Data received from substations should be aggregated – the Data Concentrator has to aggregate data before transmission to the system server • It is recommended that widely used (standard) communication protocols be utilized, e.g., IEC 870-5-101, IEC 870-5-104, DNP 3.0. Figure 1-2 shows selected substations from which data will be sent to the M&VSP System server (directly from SSiN systems or indirectly from Data Concentrators). Figure 1-2 Location of HV substations selected for the M&VSP System 1-2 Table 1 contains a list of the selected HV substations that will serve as a data source for the M&VSP System.

This infrastructure consists of cross-connecting PCM nodes connected by dedicated 2 Mbit/s links based on a SDH Exatel network. Figure 2-1 shows a fragment of this network that is relevant to the TFSM project. FMX (FMX2R3.1) multiplexers are installed in HV substations. Each FMX multiplexer is a flexible, programmable communication device that uses a standard PCM-30 time frame. These multiplexers are either terminal (end) or add-drop devices in the mentioned PCM communication network. Among other things, they enable one to create point-to-point, serial, asynchronous channels with the required capacity of 9.6 - 38.4 kbit/s. These multiplexers, as well as crossconnecting nodes, can be managed (and monitored) from one supervisory center that is located at PSE-Operator headquarters in Warszawa. Figure 2-1 PCM Network Fragment that is Relevant to the TFSM Project 2-1 The FMX multiplexer provides the following services: • data transmission in accordance with V.24, V.35, V.36, RS 530, X.21, G.703 standards • analog transmission: POTS, 2/4-wire with/without E&M • ISDN transmission Each FMX2R3.1 multiplexer is equipped with one central unit CUD, two G.703 (2 Mbit/s) ports and enables addition of up to 6 multi-port cards (with both analog and digital ports). It is possible to extend the number of multi-port cards up to 12 in case the BEC card is installed. As a terminal multiplexer („Terminal multiplexer TMX60” mode) FMX enables connection of up to sixty 64 kbit/s lines. As an add-drop multiplexer („Add-drop multiplexer DIMX2x30” mode) it enables one to connect up to thirty 64 kbit/s lines. MXS19 racks are installed in HV substations. Each rack enables installation of two FMX2R3.1 multiplexers. In case the BEC card is used, the rack is able to hold one multiplexer at most. The multi-port line cards can be replaced by up to nine line LTx (e.g. xDSL or PDH 2 x 2Mbit/s designed for fiber-glass connections) terminals. The technical characteristics of selected multiplexer cards that can be used for data transmission are given below. CPF2 – the card that enables insertion of up to 4 different interface modules: • CIM-X.21 – provides X.21/V.11 interface for either 0.3 - 38.4 kbit/s and 115.2 kbit/s asynchronous or 0.6 - 48 kbit/s, 56 kbit/s and n x 64 kbit/s (n
