At first, this paper introduce some current tests of secondary circuit in intelligent substation, then, design a performance analysis system of secondary circuit in intelligent substation based on NI platform. This kind of system analyzes analog and digital quantity messages for getting the performance of secondary system by algorithms, so that working personnel can grasp the performance comprehensively. Meanwhile, a prototype is developed to be applied in an unused intelligent substation, and the result is satisfied.

Smart Substation

Compared with traditional substation, smart substation process layer network, which has the same meaning as relay protection and safety automatic devices, is actually equivalent to the secondary circuit of traditional substation protection. Once an exception occurs in the network traffic of process layer, it will directly affect the reliability, rapidity and agility of relay protection action. According to the characteristics of network traffic of smart substation, this paper proposed a novel dynamic grey Markov model (DGMM) based network traffic prediction approach, which could assist decision making for the network performance analysis and prediction, network failures and viruses invasion warning of smart substation. Experiments demonstrated the effective and efficiency of the proposed approach, which could guarantee the security operation of power grid.

Elaeis Guineensis

Produktivitas tanaman kelapa sawit sangat dipengaruhi oleh kualitas benih yang digunakan. Pemakaian benih kelapa sawit bersertifikat dipercayai oleh petani yang kritis dalam memberikan produktivitas tanaman kelapa sawit yang bermutu dan kontinyu. Sikap dan kepuasan petani dalam menggunakan benih kelapa sawit bersertifikat merupakan hal yang perlu dicermati untuk memahami keinginan petani. Penelitian ini dirancang untuk mengamati hal tersebut. Sikap petani dianalisis dengan menggunakan pendekatan multiatribut fishbean sedangkan kepuasan dianalisis dengan menggunakan Important Performance Analysis (IPA) dan Customer Satisfied Index (CSI). Berdasarkan penelitian diketahui bahwa atribut-atribut yang menentukan sikap dan kepuasan petani adalah hasil panen, ketahan terhadap hama dan penyakit, umur tanaman, daya tumbuhbenih, efisiensi penggunaan pupuk, jenis varietas, ukuran benih, sertifikasi benih, harga benih, harga Tandan Buah Segar (TBS), kemudahan dalam akses benih, stok benih, kemudahan dalam menjual TBS, dan promosi toko.Analisis multiatribut Fishbeinmenunjukkan sikap netral terhadap benih kelapa sawit bersertifikat (76 persen). Sementara hasil CSI menunjukkan bahwa 70.04 persen petani merasa puas atas atribut-atribut pada benih kelapa sawit bersertifikat.
