This paper introduces the overseas smart substation technology scheme, describes the communication network architecture and equipment redundancy configuration in the typical overseas test smart substation scheme, and compares the similarities and differences between China’s smart substation redundancy configuration technology and the overseas smart substation configuration technology. The distribution of measurement and control functions of overseas smart substations that are different from China’s designs are explained in detail. The different architectures of overseas smart substations and China’s smart substations are illustrated. Finally, the suggestions of overseas Smart Substation and China’s smart substation are summarized.

The necessity for effective real-time monitoring and control, coupled with the developments in the fields of communication and sensor technologies, led to the emergence of the smart grid. The phasor measurement unit has emerged as an important sensor for the smart grid. The phasor measurement unit communication network is another crucial component which transfers the real-time sensor data measured by the phasor measurement unit to the phasor data concentrator for subsequent monitoring and control. Thus, its reliable operation is essential. The key parameters for assessment of reliability are the failure rate and the steady-state availability. This article presents a two-stage Markov model–aided frequency-duration technique for the reliability analysis of the phasor measurement unit microwave communication networks. Microwave communication network is a complex system as it requires several intermediate relaying towers or the microwave repeaters for communication feasibility. The Markov model explores the transition to the different system states and the frequency-duration approach estimates the frequency and duration of each of these states, thereby providing a simple and elegant means to compute the failure rates of a complex system. It provides a generalized expression for evaluating the systems availability and aids in diagnosing the components that are more prone to failure. Subsequently, this approach is used for the optimal placement of the phasor measurement units such that their resultant microwave communication networks are maximally available. Case study results for the Eastern power grid of India are presented to validate the credibility of the proposed approach.

Smart Grid Technology

An existing power grid is going through a massive transformation. Smart grid technology is a radical approach for improvisation in prevailing power grid. Integration of electrical and communication infrastructure is inevitable for the deployment of Smart grid network. Smart grid technology is characterized by full duplex communication, automatic metering infrastructure, renewable energy integration, distribution automation and complete monitoring and control of entire power grid. Wireless sensor networks (WSNs) are small micro electrical mechanical systems which are accomplished to collect and communicate the data from surroundings. WSNs can be used for monitoring and control of smart grid assets. Security of wireless sensor based communication network is a major concern for researchers and developers. The limited processing capabilities of wireless sensor networks make them more vulnerable to cyber-attacks. The countermeasures against cyber-attacks must be less complex with an ability to offer confidentiality, data readiness and integrity. The address oriented design and development approach for usual communication network requires a paradigm shift to design data oriented WSN architecture. WSN security is an inevitable part of smart grid cyber security. This paper is expected to serve as a comprehensive assessment and analysis of communication standards, cyber security issues and solutions for WSN based smart grid infrastructure.

Recently, China has become the country who has the largest and fastest-growing wind power across the world. The large-scale of wind power ask for higher requirements in the fields of Wind Power Plant (WPP) Monitoring and Control. In order to achieve that, the integrated and remote control information system for multi-WPPs is proposed in this paper. To meet the need of technical regulation for connecting WPP to power grid and improve the efficiency of WPP’s management, a framework for this integrated and remote control information system is designed, and some tentative ideas for implementing the integrated control are put forward.
