HVDC station is not in operation, i.e. de-energized. Approaches to maintenance procedures may vary across utilities. With the goal to collect the best practices, IEC recommendations with principles of the safe maintenance of HVDC converter stations were prepared by IEC TC 115. The document IEC TR 60065:2017 [10] represents the guideline based

frequent maintenance and major overhauls. Systems unique to HVDC stations are HVDC valves, and control and protection systems. Maintenance [2] is a fundamental part of the lifecycle availability and reliability. The HVDC converter equipment should be maintained in line

For a bipolar line HVDC transmission, a price of 190 kEUR/km is assumed, converter stations are estimated to 190 MEUR. Besides, for a double circuit AC transmission a price of 190 kEUR/km (each) is assumed, AC substations and series compensation (above 600 km) are estimated to 60 MEUR. It should be pointed out that the relationship between the

Oct 27, 2015These factors all impact the amount of maintenance required and must all be taken into consideration when benchmarking staffing levels and OM costs (see Figure 3). Figure 3: Equivalent Staffing Levels for Converter Stations. Outside of North America, it is common for utilities to contract out maintenance of their HVDC converter stations.

Station power plant in North Dakota and the Minnesota transmission system. The transmission line begins at a “converter station” at Coal Creek Station and ends at another converter station, the Dickinson Converter Station, near Buffalo, Minn. A unique, long-distance way to save money There is a reason that Coal Creek Station is

Installation cost of an HVdc station. components is shown in Figure 2. As it can be observed, converter assets incur almost one fourth of the cost [15]. Additional publications and guidelines for HVdc converter reliability based on power electronic components in the sub-station operation and maintenance can be found in [17]– [20].

• Second-best conductor types • Not the most rigid or strong, but light weight • A and D systems can be “linked” by the use of onverter stations. Converter stations convert AC power to DC power (and vice versa) via the lines for maintenance, repairs, vegetation management, etc. PJM©2014 09/09/2013 .

The converter stations will have periodic maintenance performed on transformers and other electrical equipment as specified by the manufacturer. The cables are monitored on a continuous basis and, unless damage is detected, they are virtually maintenance-free.

Industry Trends. HVDC Converters Market size exceeded USD 6 billion in 2018 with annual capacity installation is set to exceed 45 GW by 2025.Global market is set to grow on account of stringent energy efficiency norms favored by rapid integration of renewable power generation technologies into the grid.

between converter groups, and even more stringently, between poles. The two poles in each station are regarded as practically two stations that happen to be neighbors. The experiences from the Itaipù ± 600 kV HVDC project, also having two 12-pulse bridges in series per poles is have given important input for the structure of the system,

Monroe HVDC Converter Station, Monroe, NH. Phase/Converter Terminal Retirement. The Monroe Converter Station project consisted of the decommissioning, removal, and/or relocation (on-site) of most HVDC Phase 1 facilities; including the converter building, valve hall and associated equipment, and an underground storage tank for an oil-water separator system.

Expansion, replacements, and maintenance are integrated, prioritized in terms of asset criticality and risk, and directed at meeting reliability and other standards at lowest total economic cost. Asset management plans deliver on the transmission asset management strategy through an optimized funding and resourcing plan.
