Shulou(Shulou.com)11/24 Report--

Driven by the wave of digitization, the application of intelligent power equipment is becoming more and more popular. Among them, as the core link of the modern power system, the power monitoring gateway monitors the operation status of the power supply system in real time through data acquisition, transmission and analysis, which provides an important guarantee for the stable operation and optimal dispatching of the power system.

As the carrier of the data in the power gateway, the quality and performance stability of the memory play a decisive role in the performance of the power monitoring system, and then have a profound impact on the operation of the whole power system.

So, what are the current challenges facing the power industry in the direction of data storage? For electric power enterprises, how to choose reliable storage devices?

Challenge 1: secure the basic guarantee of electricity consumption, and the data storage must be stable and reliable.

High quality, low / zero failure rate: the power industry has very strict requirements for equipment quality. Because once the equipment fails, the maintenance cost of the system is high, and even need to apply for power outage for maintenance, affecting the normal production and life. Storage products must be of high quality and avoid failures as much as possible.

Stable and reliable, 7-24-hour uninterrupted power supply: both residential life and enterprise production need 7-24-hour uninterrupted power supply, so the power industry has strict requirements for the continuous stability of memory.

Long life: products in the power industry have a long service life, usually starting with five years, and some even require a service life of more than 8 to 10 years, and the corresponding storage scheme needs to meet the long life standard.

Stable supply demand: in order to ensure the consistency of products, the power industry also puts forward high requirements for the stable supply capacity of memory manufacturers, and then puts forward higher standards for the R & D capacity and manufacturing capacity of memory manufacturers.

Challenge 2: how to support production scheduling decisions timely and efficiently because of the large volume and variety of power data?

The data transmission speed is fast and the precision is high: the volume of power monitoring data is huge, including power load information, power supply information, intelligent meter operation information and so on. In order to ensure the timely and accurate transmission of power monitoring data and to make effective use of the decision-making mechanism, power gateways need to have efficient data acquisition, scheduling and transmission capabilities to avoid partial data loss and confusion.

Multi-thread management, low latency: the business process of the power industry is complex, involving many professional areas and different departments, and the data transmission within the enterprise and across organizations and regions is increasing day by day. Staff in departments such as marketing, scheduling, equipment and customer service may need to access relevant data at any time, so memory is required to have strong multitasking management and high performance capabilities. In order to avoid the stutter phenomenon caused by multi-thread simultaneous access.

The difference between peak and valley leads to data load imbalance: considering the difference between peak and trough periods in power demand, memory performance needs to be stable and consistent to ensure that data storage can be carried out in an orderly manner at any time.

Challenge 3: the power industry is related to the national economy and people's livelihood, how to ensure its security?

Data security is facing the test: as a key production factor, the security protection of power data is very important for the sound operation of power grid business.

According to the first-quarter information operation and network security report released by Fujian Electric Power, the company monitored and blocked more than 560500 network attacks and blocked 6341 high-risk attack source addresses.

Therefore, the memory must adopt data encryption technology to improve the level of data security protection and strictly prevent sensitive data leakage in order to ensure the security and integrity of power data.

Challenge 4: how to deal with bad weather in outdoor work?

Complex and abnormal environmental conditions: in actual operation, the equipment of the power monitoring system may encounter a variety of complex and changeable environments, such as extreme temperature changes and abnormal power outages. Therefore, the memory must have the ability to work outdoors and be able to work in high and low temperatures, bad weather and other conditions without worry.
