𝐁𝐚𝐭𝐭𝐞𝐫𝐲 𝐒𝐢𝐳𝐢𝐧𝐠 & 𝐃𝐢𝐬𝐜𝐡𝐚𝐫𝐠𝐞 𝐀𝐧𝐚𝐥𝐲𝐬𝐢𝐬 (𝐏𝐚𝐫𝐭 1) When AC power is lost, batteries will provide power to critical loads and control circuits for a specified time period so that the AC power source can be recovered or the critical equipment can be adequately shut down. In complying with 𝐈𝐄𝐄𝐄 𝐬𝐭𝐚𝐧𝐝𝐚𝐫𝐝 485, the battery sizing module shall determine the 𝐧𝐮𝐦𝐛𝐞𝐫 𝐨𝐟 𝐬𝐭𝐫𝐢𝐧𝐠𝐬, 𝐧𝐮𝐦𝐛𝐞𝐫 𝐨𝐟 𝐜𝐞𝐥𝐥𝐬, and 𝐜𝐞𝐥𝐥 𝐬𝐢𝐳𝐞 of a battery for a designated 𝐝𝐮𝐭𝐲 𝐜𝐲𝐜𝐥𝐞. The number of cells is determined to satisfy the maximum system voltage during the battery charging period and the minimum system voltage during the battery discharging period. The number of strings and cell size are determined to provide sufficient power to the load cycle considering the minimum system voltage and the minimum operating temperature. It also considers different factors that affect battery performance, such as design margin, aging compensation, initial capacity, and temperature.    The duty cycle for the battery can be a summation of the duty cycles of all the loads that the battery is to supply power for. It can also be calculated using 𝐃𝐂 𝐥𝐨𝐚𝐝 𝐟𝐥𝐨𝐰, which considers different characteristics of constant power load and constant impedance loads, their variations to voltage changes, branch voltage drop, and losses.

Tips and hints about #ATS (#Automatic_Transfer_Switch) Operation For example, 2 out of 4 (2/4) 1-   In normal operation, both transformers are in service while each one supplies a section of the panel. 2-   If one of the two transformers is out of service, the bus coupler is closed and the served transformer supplies both sections. Take care of its rating or you should shed some loads. 3-   If both transformers are out of service, the generator operates for supplying emergency loads. Electrical & mechanical interlocks shall be guaranteed between Q2 & Q3. 4-   For point 3, if transformer 1 is out due to fault conditions (trip case), neither Q2 nor bus coupler closes as there is a probability that the fault occurs at section B. 5-   If Q1 & BC are in service and BC trips, Q2 is not permitted to close as there is a probability that the fault occurs at section A. 6-   If any of the 3 sources is out due to fault conditions (trip case), BC is not permitted to close as it will feed the fault and trips also.   Follow us for more technical posts. #ETAP #Powersystem #Contingency #Electricnetwork #DIgSILENT #PowerFactory #PSSE #PSCAD #Loadflow #SmartSolutionsTechnical #consultations #Training  

𝐈𝐧𝐭𝐞𝐫𝐧𝐚𝐥 𝐃𝐂 𝐀𝐫𝐜 𝐅𝐥𝐚𝐬𝐡 𝐂𝐚𝐥𝐜𝐮𝐥𝐚𝐭𝐢𝐨𝐧𝐬 (𝐩𝐚𝐫𝐭 3) How the inter-string protection affects the DC arc flash results as per 𝐀𝐒/𝐍𝐙𝐒 5139 standard. As it is shown in the Figure, there are 5 possible locations of faults:   𝐋𝐨𝐜𝐚𝐭𝐢𝐨𝐧 𝐀: Fault @ single cell or module 𝐋𝐨𝐜𝐚𝐭𝐢𝐨𝐧 𝐁: Fault @ Multiple cells or modules 𝐋𝐨𝐜𝐚𝐭𝐢𝐨𝐧 𝐂: Fault @ mid-string. 𝐋𝐨𝐜𝐚𝐭𝐢𝐨𝐧 𝐃 & 𝐄: Fault @ DC Bus or @ the end of the string It is worth noting that different fault contributions shall be considered in determining the possible arc flash incident energy at the specified fault location. In other words, fault contribution from the 𝘗𝘊𝘚, 𝘩𝘦𝘢𝘭𝘵𝘩𝘺 𝘴𝘵𝘢𝘤𝘬𝘴, 𝘢𝘯𝘥 𝘧𝘢𝘶𝘭𝘵𝘺 𝘮𝘰𝘥𝘶𝘭𝘦𝘴 (each with its corresponding protection device). For every fault path, the arcing time is computed from the tripping characteristics of the protection device, or it will be assumed 2 seconds if the fuse’s operation is not considered. Finally, the worst incident energy level is tackled in assessing the proper PPE category. Therefore, our 𝐞𝐧𝐡𝐚𝐧𝐜𝐞𝐝 𝐭𝐚𝐢𝐥𝐨𝐫-𝐦𝐚𝐝𝐞 𝐀𝐈 𝐭𝐨𝐨𝐥 is your best target in this dilemma. With its aid, you can determine the arcing current, time, and incident energy from the diverse fault paths. Moreover, both live and maintenance operations of the BESS are examined along with various SoC levels. 𝘊𝘰𝘯𝘧𝘪𝘥𝘦𝘯𝘵𝘪𝘢𝘭𝘭𝘺, this tool has already been used for various MEGA projects worldwide.    For further information, kindly contact us through the page or our Mail: info@smartsolutions-tech.com Mobile:+201004726360 website: https://lnkd.in/duy8QmRd #SmartSolutionsTechnical #consultations #Training #ETAP #EPLAN #PSSE #REVIT #PSCAD #EMTP #ATP #DIGSILENT #CYME #PVSYST #HOMER #NEPLAN #DC_Short_Circuit #Coordination #Protection #arcflash #DC_arcflash #Gridcode #Gridimpact

𝐈𝐧𝐭𝐞𝐫𝐧𝐚𝐥 𝐃𝐂 𝐀𝐫𝐜 𝐅𝐥𝐚𝐬𝐡 𝐂𝐚𝐥𝐜𝐮𝐥𝐚𝐭𝐢𝐨𝐧𝐬 (𝐩𝐚𝐫𝐭 2) In this post, we will discuss how the incident energy level is evaluated inside the BESS considering the operation of the protection device. Typically, most projects utilize semiconductor fuses as the main protection devices inside the stack. Based on the recommendations of 𝐀𝐒/𝐍𝐙𝐒 5139 standard as it is shown in the Figure, the fault may occur at various locations: 𝐋𝐨𝐜𝐚𝐭𝐢𝐨𝐧 𝐀: Fault @ single cell or module 𝐋𝐨𝐜𝐚𝐭𝐢𝐨𝐧 𝐁: Fault @ Multiple cells or modules 𝐋𝐨𝐜𝐚𝐭𝐢𝐨𝐧 𝐂: Fault @ the string side of the protection device. 𝐋𝐨𝐜𝐚𝐭𝐢𝐨𝐧 𝐃 & 𝐄: Fault @ DC Bus or @ the end of the string For locations A & B & C, the arcing time is considered as 2 𝘴𝘦𝘤𝘰𝘯𝘥𝘴 without a clearing action from the fuse. However, for faults at D & E, the fast-acting fuse is assumed to operate in a very short time minimizing the incident energy level as much as possible. Most international standards recommend implementing fuses with 𝘢𝘙, 𝘢𝘉𝘢𝘵𝘵, 𝘰𝘳 𝘨𝘉𝘢𝘵𝘵 utilization category. In this context, we are delighted to perform these calculations inside the 𝐁𝐄𝐒𝐒 with the aid of our commercial AI tool. Additionally, various SoC levels of the BESS can be investigated automatically printing the required level of PPE along with gloves rating.

𝐈𝐧𝐭𝐞𝐫𝐧𝐚𝐥 𝐃𝐂 𝐀𝐫𝐜 𝐅𝐥𝐚𝐬𝐡 𝐂𝐚𝐥𝐜𝐮𝐥𝐚𝐭𝐢𝐨𝐧𝐬 (𝐩𝐚𝐫𝐭 1) Let’s discuss how the arc flash incident energy is calculated inside the 𝐁𝐄𝐒𝐒 with no string protection besides the string main protection. Based on the recommendations of the 𝐀𝐒/𝐍𝐙𝐒 5139 standard as shown in the Figure, the fault may occur at various locations: 𝐋𝐨𝐜𝐚𝐭𝐢𝐨𝐧 𝐀: Fault @ single cell or module 𝐋𝐨𝐜𝐚𝐭𝐢𝐨𝐧 𝐁: Fault @ Multiple cells or modules 𝐋𝐨𝐜𝐚𝐭𝐢𝐨𝐧 𝐂 & 𝐃: Fault @ DC Bus or @ the end of the string For these locations, the arcing time is assumed to be 2 𝘴𝘦𝘤𝘰𝘯𝘥𝘴 without any protection or clearing device. These locations differ from the magnitude of arcing voltage and current which in turn affects the incident energy level (Cal/cm2). Actually, the incident energy level is accumulated by increasing the number of faulty modules inside the stack. However, with the aid of our professional team led by Prof. Attia El-Fergany and 𝘈𝘐 𝘵𝘢𝘪𝘭𝘰𝘳-𝘮𝘢𝘥𝘦 𝘵𝘰𝘰𝘭𝘴, we are delighted to share with clients all over the world our competency in delivering the DC short circuit & DC arc flash studies.

Meanwhile, 𝐍𝐅𝐏𝐀 70𝐄 is considered the only international standard that provides guidance for DC arc flash calculations. There are two methods for calculating the DC arcing currents: 1-   Maximum power technique (𝘋𝘰𝘢𝘯 method) 2-   Detailed arcing current and energy calculation method (𝘈𝘮𝘮𝘦𝘳𝘮𝘢𝘯 method) 𝐃𝐨𝐚𝐧 method is a conservative approach while 𝐀𝐦𝐦𝐞𝐫𝐦𝐚𝐧 method is a trusted technique in the industry due to its accuracy in evaluating the incident energy. However, as per 𝐀𝐒/𝐍𝐙𝐒 5139:2019, the arc flash incident energy along with arc flash protection boundaries need to be determined at various locations inside the BESS. Three fault scenarios are investigated inside the 𝐀𝐒/𝐍𝐙𝐒 5139 which will be discussed later in the upcoming posts: a-   𝐅𝐚𝐮𝐥𝐭 1: No protection (assuming an arcing time of 2 seconds). b-   𝐅𝐚𝐮𝐥𝐭 2: String protection (Inter-faults between string modules). c-    𝐅𝐚𝐮𝐥𝐭 3: String and inter-string protection (Fault @ multiple cells or modules or at the DC bus). Unfortunately, there is a lack of commercial software that provides DC arc flash calculations between the string modules or cells (BESS internal calculations). Most commercial software calculates the DC arc flash incident energy at the main DC buses. 𝐈𝐧 𝐭𝐡𝐢𝐬 𝐫𝐞𝐠𝐚𝐫𝐝, we are thrilled to announce that we have developed our own commercial AI tool that performs the DC arc flash hazard analysis at any location of your 𝐁𝐄𝐒𝐒.
