Defender prepares for ESS As the demand for electricity constantly increases, so does the need to store energy (as well as to produce it). Like all electrical installations, energy storage systems require specific equipment protection. Energy Storage Systems (ESS) is a growing technology right now. ESS is installed in places to enable energy management, such as peak control or frequency regulation, or for renewable energy storage for photovoltaic or wind power plants. The importance of such equipment makes the interruption of their work unacceptable, so measures must be taken to limit damage due to external forces. One of the risks that should be considered is possible damage due to transient voltages generated by lightning or by changing functions. The deployment of ESS has shown the limited power of these devices, including battery systems. Specialists in this technology have confirmed that their low power supply voltage (U w ) can lead to serious system failure. Protection prepared for ESS Surge Protection Device (SPD) is widely used in AC power networks to protect equipment connected to them against transient voltages.
Testing standards (IEC61643-11), and selection and installation Job Function Email Database guidelines (IEC61643-12, IEC60364-5-534) have existed for many years. They define reliable products as well as their selection and implementation. However, regarding DC power networks, there is no standardization at the time of writing. In fact, standards for ground protection for DC power continue at the international level (IEC). It is, however, expected that by the end of 2021 the following standards will be in place: IEC 61643-41: Test methods for surge protection for low voltage DC lines IEC 61643-42: Selection and installation of surge protection for low voltage DC lines This upcoming IEC61643-41 standard will be a departure from the existing standards of surge protection devices for AC networks (IEC61643-11) and parameters (I n , OR c , Mo max , OR p …) and the test procedures will be similar because they will be compiled in a new book, common to the two books. The IEC 61643 series is moving towards a new philosophy. A new document (IEC61643-01) will gather all the definitions and tests common to the various applications of SPDs (AC power, PV power, Dataline, DC power) and classification standards (IEC61643-11, IEC6163-21 , IEC61643-31).
And the upcoming IEC61643-41) will focus only on tests specific to the application. Regarding the safety tests that simulate the end of life of the SPD - such as thermal overload or short-circuit behavior - the procedures are similar as well as the necessary methods to achieve the requirements, namely the use of internal connectors to withstand runaway thermal tests, and associated fuses to withstand short-circuit tests. Current status Regarding the obligation of protection against temporary overload for ESS equipment, the current standard for electrical installation IEC60364 does not give information, requirements or recommendations on this point. The reason for this is that IEC60364 describes low-voltage installations connected in AC power supplies (not DC current), and enforces protection requirements against surge voltages only at the entrance to the external network. This is not the case for the localization of the DC part of the ESS. Transient over-voltage Experts in ESS equipment have noticed the potential reduction in the energy consumption of these equipment - especially in battery systems - and due to the important need for service continuity, they recommend the use of surge protectors in their terminals. Background protection on the AC unit is also recommended. For these reasons and result.
