GB/T 22390.1-2008Control and protection equipment of HVDC transmission systems - Part 1: Operator control system (English PDF)

Foreword

According to the 2003 National Science and Technology Science and Technology Platform project focused "DC power transmission system core technology and infrastructure standard Research "(Project No. 2003DIA7J034) requirements formulated standard" HVDC system control and protection equipment. " GB/T 22390 "HVDC system control and protection equipment" is divided into six parts.

--- Part 1. Operator Control System;

--- Part 2. AC and DC station control system equipment;

--- Part 3. DC pole control system equipment;

--- Part 4. DC system protection equipment;

--- Part 5. DC line fault location device;

--- Part 6. Converter Station transient fault recorder. This section GB/T Part of 122,390. This section proposed by the China Electrical Equipment Industry Association and the China Electricity Council. This part of the National Standardization Technical Committee of HVDC equipment (SAC/TC333) centralized. This part mainly drafted by: XJ Group Corporation, Nanjing NARI-RELAYS Electric Co., Ltd., Beijing Network of DC engineering technology Ltd., China Southern Power Grid Co., Ltd., Xuchang Relay Research Institute, Chinese Academy of Sciences electricity.

HVDC system control and protection equipment Part 1. Operator Control System

1 Scope

China's national standard for the operator control system of a high voltage direct current transmission scheme. It is Part 1 of GB/T 22390 and specifies the technical requirements, the test methods, the inspection rules, the packaging, transport and storage, the marking and documentation, the complete supply and the quality assurance for the operator control system of an HVDC transmission system. China built more HVDC than the rest of the world combined, because the generation is two thousand kilometres from the load and only direct current moves that much power that far economically. An HVDC link is not a line but a machine: converter stations at each end, thyristor or IGBT valves, converter transformers, filters, and above all a control system that determines every quantity in the scheme. Unlike an AC line, where the power flow follows from the network, in an HVDC link the power flow is whatever the controls order, to the megawatt, and it can be reversed or driven to zero in a fraction of a second. That capability is what makes the link valuable and what makes the control system the plant. This part covers the top layer of it, the layer the operator sees and uses: the human-machine interface, the displays and the mimic, the sequences by which the link is started, stopped and its power order changed, the alarm and event handling, the interlocks that prevent an unsafe command from being issued, the data logging and the interface to the dispatch centre. The requirements are demanding for a reason that is not obvious: an operator error on an HVDC link is not a local fault, because the link may be carrying several gigawatts and losing it is a system event for the whole grid at both ends. Issued on 24 September 2008 and in force since 1 August 2009.

This section GB/T 22390 specifies the technical requirements of ± 500kV HVDC Transmission System Operator Control System Test Methods, inspection rules, packaging, transportation, storage, marking, labeling, instruction manual, complete sets of supply and quality assurance. This section applies to ± 500kV HVDC Transmission System Operator Control System (hereinafter referred to as system).
