This technical article describes detailed planning and design phases of a new 220 kV Gas-Insulated Switchyard (GIS) in a 450 megawatt (MW) coal-fired combined heat and power plant (CHP) that was being considered for Ulaanbataar, Mongolia. The project is assumed to have been abandoned or canceled due to public opposition brought on by Ulaanbaatar’s poor air quality. Too bad, because no renewable energy project can actually replace this one. However, the subject of this article is a 220 kV Gas-Insulated Switchyard (GIS), its layout, specification, busbar configuration, cost and finally its interconnections with generation plant.

There has been a lot of talk on renewable energy to reduce carbon foot print. This is definitely the way to go to implement EV and hydrogen fuel cell technology as they are dependent on electricity for charging battery and to generate hydrogen. To use fossil fuel for charging is simply not doing the job. But the low hanging fruits are really to implement energy efficiency not only in using energy efficient equipment but also in our design of building services and control, and lastly on how we use our energy in the building. One strategy adopted by the government agencies is to increase the room design temperature. Back to psychometric, when room design temperature is increased, the supply air required to cool down the space load would be reduced without changing the supply air temperature from simple energy equation. This would save fan energy. If building is not very well insulated, we may also be able to reduce the heat gained from building envelope as the temperature difference between outside and inside of building is less. Learn HVAC psychometric, learn energy efficiency in structured manner as a HVAC engineer. https://lnkd.in/gTUJ_DYj

Magnetocaloric heat pump for residential applications: Researchers in Denmark built a magnetocaloric heat pump prototype for heating purposes in residential buildings. Although more work is needed to bring the system closer to commercial maturity, it can reportedly achieve a 36.9 % heating power improvement with measurement feedback control. #Renewables #Energy #Technology

As PVFARM continues to gain traction within the industry, we're seeing increased interest in one of its capabilities: repowering projects. We are fortunate to have the smartest superusers who began highlighting the importance of this topic a year ago, playing a pivotal role in helping us develop the repowering functionality. Imagine you developed a project several years ago. With new financial opportunities emerging through Power Purchase Agreements, advanced battery solutions, or other innovations, you decide it's time to repower. Here’s how PVFARM can help with this: 1️⃣ Importing existing solar PV layout from AutoCAD or Civil3D into PVFARM 2️⃣ Upgrading the solar modules across the entire layout while keeping the existing racking system intact. 3️⃣ Overhauling combiner boxes, inverters, and transformers require reblocking and rebalancing the entire layout. 4️⃣ Obtaining instant cost and energy efficiency feedback for different equipment setups to choose the best. Let's dive into concrete data to illustrate the impact: 🔹 Initially, the system with Module LR4-72HBD-425M and a Sungrow 3600 kW central inverter produces 203.1 MWdc across 46 blocks, averaging an Inverter Loading Ratio (ILR) of 1.225. 🔹 Upgrading to Module LR5-72HBD-555M enhances capacity to 265.2 MWdc for the same number of blocks, raising the average ILR to 1.60. 🔹 This upgrade leads to significant inefficiencies unless the combiner boxes, inverters, and transformers are reblocked and rebalanced. 🔹 Retaining the Sungrow 3600 kW with 400 A combiner boxes under the old configuration still allows for a capacity of 265.2 MWdc, but now spread over 58 blocks with an average ILR of 1.27. 🔹 Alternatively, adopting a new Sungrow 4400 kW inverter skid maintains the 265.2 MWdc and 58 blocks while preserving the average ILR at 1.27. Check out the example above explained in more detail in the video below.

How Risky is Solar Panel Installation?

Analysis of Common Failure Resons of Solar Panel Junction Boxes there are several common failure reasons of solar panel junction boxes that can lead to significant issues if not addressed properly. In this article, we will delve into the main reasons behind these failures and provide insights on how to prevent them effectively. 🔰 Component welding process quality problem There are cold solder joints at the connection between the diode pin and the copper conductor, and at the connection between the bus bar and the copper conductor in the junction box. When the photovoltaic module is shadowed or other problems cause the bypass diode to be turned on, the cold solder joint will generate heat. When the heat accumulated at the cold solder joint exceeds the thermal deformation temperature of the insulating material of the junction box, the junction box will age and deform. The longer the bypass diode is turned on, the greater the risk of deformation and aging of the junction box. When the temperature is greater than the upper limit of the diode junction temperature, the high temperature will cause the bypass diode to undergo thermal breakdown and damage, or even burn the junction box. 🔰 Component Sealing Process Quality Issue There was contamination during the gluing process between the junction box and the photovoltaic module backplane, which led to the junction box and the silicone separating failure later. 🔰 Shadowing, hidden cracks, etc. Photovoltaic modules are in shadow, hidden cracks, local hot spots and other conditions for a long time, which causes the bypass diode to be in continuous working state for a long time, causing the junction temperature of the bypass diode to rise. When the junction temperature accumulates to a certain level, the bypass diode will fail due to thermal breakdown. If not handled in time, the heat accumulation will reach the deformation temperature of the junction box insulation material, and the junction box will deform and age. In severe cases, it may cause the junction box to burn out. 🔰 Lightning Strike When a photovoltaic module is struck by lightning, the bypass diode will be instantly broken down by the high voltage. When the rain stops and the sky clears, as the normal module current flows through the failed diode for a long time, the diode will heat up. When the heat accumulates to a certain extent, it will cause the junction box to age and deform, and even cause the junction box to burn out. understanding the common failure reasons of junction boxes and implementing preventive measures is critical for maintaining the long-term performance and safety of photovoltaic systems. By addressing issues related to welding processes, component sealing, shadowing, and lightning strikes, system owners can minimize the risk of junction box failures and ensure the reliable operation of their solar power systems.
