27、(E) INTRODUCTION The standard is structured in eight clauses: a) Clause 1 Scope b) Clause 2 Normative references c) Clause 3 Definitions d) Clause 4 General e) This clause addresses the purpose of this standard, the HVDC system structure, the control and protection structure, the logical steps of co
28、mmissioning, the structure of the system test and that of the system commissioning standard. f) Clause 5 Converter station test g) This clause addresses the commissioning of converter units and verifies the steady state performance of units as well as switching tests. h) Clause 6 Power transmission
29、tests i) This clause concerns the commissioning of the transmission system, and verifies station coordination, steady-state and dynamic performance, interference, as well as interaction between the d.c. and a.c. systems. j) Clause 7 Trial operation k) After completion of the system test, the period
30、of trial operation is normally specified to verify the normal transmission. l) Clause 8 System test plan and documentation Clauses 5 to 7 comprise individual sections providing an introduction and covering objects, preconditions and procedures and general acceptance criteria as well as detailed desc
31、riptions of the individual tests. BS EN 61975:2010Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 27/01/2011 06:41, Uncontrolled Copy, (c) BSI61975 IEC:2010(E) 7 HIGH-VOLTAGE DIRECT CURRENT (HVDC) INSTALLATIONS SYSTEM TESTS 1 Scope This International Standard applies to system tests for high-
32、voltage direct current (HVDC) installations which consist of a sending terminal and a receiving terminal, each connected to an a.c. system. The tests specified in this standard are based on bidirectional and bipolar high-voltage direct current (HVDC) installations which consist of a sending terminal
33、 and a receiving terminal, each connected to an a.c. system. The test requirements and acceptance criteria should be agreed for back-to-back installations, while multi-terminal systems and voltage sourced converters are not included in this standard. For monopolar HVDC installations, the standard ap
34、plies except for bipolar tests. For the special functions or performances that are claimed by specific projects, some extra test items not included in this standard should be added according to the technical specification requirements. This standard only serves as a guideline to system tests for hig
35、h-voltage direct current (HVDC) installations. The standard gives potential users guidance, regarding how to plan commissioning activities. The tests described in the guide may not be applicable to all projects, but represent a range of possible tests which should be considered. Therefore, it is pre
36、ferable that the project organization establishes the individual test program based on this standard and in advance assigns responsibilities for various tasks/tests between involved organisations (e.g. user, supplier, manufacturer, operator, purchaser etc.) for each specific project. 2 Normative ref

41、power between both terminals NOTE It is also referred to as an “end to end test”. 3.2 Operation state terms In the d.c. system, there are 5 defined states: earthed, stopped, standby, blocked, de-blocked. 3.2.1 earthed state in which the pole or converter is isolated and earthed on the a.c. and d.c.
42、sides and no energizing of the pole or converter equipment is possible NOTE The earthed state provides the necessary safety for carrying out maintenance work, and is the only one that permits the pole or converter maintenance. In this state maintenance work is possible on the converter transformers,
43、 the isolated and earthed part of the a.c. high voltage bus equipment, d.c. and valve hall installed equipment of this pole or converter. 3.2.2 stopped/isolated state in which the pole or converter is isolated from the a.c. and d.c. side, but all the earthing switches are open NOTE In this state the
44、 d.c. yard can be prepared for power transmission (earth electrode line, pole and d.c. line connect). 3.2.3 standby state which is to be used when the d.c. system is not being utilized but is ready for power transmission NOTE In this state the converter transformer is to be ready; tap-changer is aut
45、omatically brought to the start position, which ensures that the transformer will be energized with minimum voltage to minimize the inrush current. The disconnector of the a.c. bay should be closed, but the circuit breakers in the feeding bay of the converter transformer should be open. In this stat
46、e the d.c. configuration can still be changed (earth electrode line, pole and d.c. line connect). 3.2.4 blocked state in which the pole is prepared to transmit power at a moments notice NOTE The converter transformer is connected to the energized a.c. bus by means of closing of the respective circui
47、t breaker. The valve cooling system is ready for operation if the cooling water conductivity, flow and temperature are within the specified limits. A defined d.c. configuration shall have been established. Further changes are not possible in this state. The thyristor pre-check is carried out after t
48、he converter transformer has been energized. The pre-check is considered as passed when in every valve the redundancy is not lost. To change the blocked state, the states stopped, standby and de-blocked are selectable. 3.2.5 de-blocked state representing the following two operating modes: power tran
49、smission and open line test NOTE Power transmission is the normal operating mode. In the de-blocked status the pole transmits power in normal operating mode if both terminals are in the deblocked stage and there is a voltage difference between the terminals. A minimum number of a.c. filters should be available.
