scope:

This document is intended to be part of a series of standards that formalizes the access interfaces of Power System Monitors/Controllers (PSMC). The PSMC is an intelligent, user-configured, hardware/software system. This system incorporates one or more functional capabilities to detect analog and binary input signals, process and store acquired data, report information, and control power systems, including power plants and power plant support systems.

This standard specifies requirements for the human-machine user access language of power systems monitors/controllers. The standard defines language elements that support management functions that include, but are not limited to, Operations, Administration, Maintenance, and Provisioning (OAM&P) functions as defined in other American National Standards such as American National Standard for Telecommunications - Operations, Administration, Maintenance, and Provisioning (OAM&P) - Principles of Functions, Architectures, and Protocols for Telecommunications Management Network (TMN) Interfaces, ANSI T1.210-1993. The present issue of this standard addresses only the commands and responses that are required for human-machine interaction, that is:

- human-initiated commands that are capable of being recognized by a PSMC;

- human-interpretable responses from the PSMC resulting from recognizable humaninitiated commands; and

- human-interpretable responses from the PSMC resulting from nonrecognized human-initiated inputs, e.g., improperly formed commands or typing errors.

Future standards will address:

- interfaces between PSMCs and Operations System (OS)-like systems that perform systems management functions but are not located within a Telecommunications Management Network (TMN) environment;

- interfaces between power systems-oriented network elements and OSs that are located within a TMN environment

Purpose

Changes in the telecommunications industry have increased the need for detailed monitoring of power systems. However, no single standard exists that specifically addresses communications between machines, humans, and telecommunications power plants. The purpose of this document is to provide a user access language, i.e., a set of commands and responses, for the support of power systems management functions. The telecommunications industry, including both product developers and users of these products, stands to benefit from these standards in a number of ways:

- reduced development costs;

- reduced training costs;

- increased interoperability among a broad range of power systems monitoring and control equipment.
