Abstract

The effective use of microprocessors in power plant systems can provide many benefits, including smaller component size and lighter equipment weight, easier maintainability enhanced economy. Because power receiving systems are ordinarily quite large and complicated, consisting of numerous subsystems, regular maintenance work usually takes a long time. NTT has thus developed an advanced, highly reliable power receiving system which effectively employs microprocessors to reduce maintenance work. This system mainly consists of the following equipment: (1) power receiving panel (PRP); (2) high voltage transfer branch panel (TBP); (3) transformer panel (TRP); (4) low voltage branch panel (LBP); and (5) power system supervision and control equipment (PS SVC). The PRP, TBP, TRP and LBP have achieved downsizing and easier maintainability using microprocessors and a PS SVC was designed to be less than unavailability target value using microprocessors. This paper describes the background of microprocessor application to NTT telecommunication power plant, outlines of this new power receiving system, its operation and maintenance, and how control equipment reliability is designed.<>

先进、可靠的电力接收系统，适用于电信电厂

在电厂系统中有效地使用微处理器可以提供许多好处，包括更小的部件尺寸和更轻的设备重量，更容易维护，提高经济效益。由于电力接收系统通常非常庞大和复杂，由许多子系统组成，因此定期维护工作通常需要很长时间。因此，NTT开发了一种先进的，高度可靠的电源接收系统，有效地采用微处理器来减少维护工作。本系统主要由以下设备组成:(1)电源接收面板(PRP);(2)高压转移支路面板(TBP);(3)变压器面板(TRP);(4)低压支路面板(LBP);(5)电力系统监控设备(PS SVC)。PRP、TBP、TRP和LBP使用微处理器实现了小型化和易于维护性，并且PS SVC被设计为使用微处理器小于不可用目标值。本文介绍了微处理器在NTT电信电厂应用的背景、新型电力接收系统的概况、运行维护以及控制设备可靠性设计。
