Wind Power

System Introduction

Based on computers, communication devices, and test control units, the wind power monitoring system provides a basic platform for real-time data collection, switch status monitoring, and remote control of wind power plants. It can work with detection and controls devices to form an arbitrarily complex monitoring system. It plays a vital role in the monitoring of wind power plants by helping enterprises eliminate information silos, reduce operating costs, improve production efficiency, and accelerate the speed of responding to anomalies in the process of power transformation and distribution. Figure 4.4 shows its system architecture Currently, the electric power monitoring system is vertically connected to dispatching planes 1 and 2 and the centralized control center of the wind power plant.

ICS Information Security Assurance Framework

ICS Security Assurance Principles

In response to related compliance requirements put forward by the industry and the country, the ICS information security assurance framework will be developed to combine both technology and management, taking full account of the enterprise’s business requirements and ICS operating characteristics. By switching ICS protection from deployment of security policies to that of security capabilities, such a framework aims to enable an all-around improvement in security technology and management capabilities for the purpose of integrating management, control, and defense. With this framework, enterprises’ security capabilities will gradually cover system go-live, operating, O&M, and inspection, achieving closed-loop security control and management for ICSs. (mais…)

2.4 ICS Security Trend

All in all, with IT and OT converging at a rapid pace, ICSs will be exposed to more threats that are evolving faster and faster. The threat evolution is reflected in the following aspects: (mais…)
